  • Science Wing (main entrance) - Monday to Friday 6:00 a.m. to 7:00 p.m. 
  • ARC entrance - Monday to Friday 8:30 a.m. to 10:00 p.m. Saturdays and Sundays from 12:00 p.m. to 6:00 p.m. 
  • Any access outside the hours listed above will require a call to Campus Safety at 416-287-7398 to provide entry for staff and faculty.
  • All other buildings will remain locked and only accessible to those with authorized fob access.

Study Spaces

  • There is no study space available in the Bladen Wing for the month of January 2022.
  • All study space on UTSC property is strictly for current U of T students only. 

UTSC Library

More information and UTSC Library hours of operation.

Library help for research, teaching, and learning is available online.

In short, no. You must be fully vaccinated to come to campus.

If you have a class that you must complete which is only held in person, please contact your department or the campus registrar.

Those seeking an exemption for medical or other protected human rights grounds can make a request through the University’s Vaccination Exemption Request Portal via the Enterprise Service Centre (ServiceNow). Forms are now available and completed requests can be uploaded for review beginning September 2. Please note that approval is not guaranteed.

Individuals who are awaiting their final vaccine dose or who have received a University-approved exemption must participate in the University’s rapid screening program and may be subject to additional safety measures. At-home screening kits will be provided to these individuals and available for pick-up at no cost, along with an instructional video. Results must be uploaded in UCheck at least twice weekly (subject to change depending on public health conditions), and a negative result will be required before coming to University-owned or operated premises. Individuals who are neither fully vaccinated nor enrolled in the rapid screening program by September 13 cannot come to any University premises. Rapid screening cannot be used as an alternative to vaccination without an approved exemption.


For the most up-to-date hours of operation for food services on campus, please visit the Eating on Campus website.

Student events and programming will continue remotely, with some in-person or hybrid events available. You can access the Student Programs calendar on the Career Learning Network site.

Library Access

Library help for research, teaching, and learning is available online.

UCheck is the easiest and most secure way to complete the required self-assessment and generate a COVID-19 risk status prior to coming to campus. Your risk status (e.g., “red” or “green”) is securely shared with the University, but individual responses to the UCheck self-assessment questionnaire are not accessible by the institution. More details on how to use UCheck, including how we are keeping this data private, are available at

In the event that you are unable to access the UCheck online self-assessment prior to coming to campus, please complete UCheck as soon as you are able to, once on campus. Alternatively, if choose not to use UCheck, you can access an offline or paper-based log to complete your self-assessment and document your risk status here.

Any student who receives a red status after completing a self-assessment should follow the directions provided via UCheck or on the offline or paper-based log.

Thank you for ensuring a safe, healthy environment and campus.

  1. Ontario’s evolving response to COVID-19 continues to present all of us with unexpected challenges in our studies, and in our daily life. Provincial regulation and public health guidance now require that post-secondary institutions implement COVID-19 health screening via a self-assessment for anyone coming to campus. In order to comply with these directives, a self-assessment is now required for all members of our community, including students, each day they visit any of the three U of T campuses or any other property owned or operated by U of T.
  2. There are two ways that individuals can complete the required self-assessment and generate a risk status: by using UCheck, or be completing an offline or paper-based log each time you come to campus.

While space is limited and physical distancing will be applied, students who do not have access to computer resources at home can access Wi-Fi and computer resources in the Library. Virtual resources and services continue to be available for students.

Please check the SCSU website periodically for more information.

General Campus Updates

As recently announcedOpens an external site in a new window in an all-community message, the University is increasing in-person teaching and other activities as of Monday, February 7, 2022. We are supporting UTSC departments to offer as many in-person opportunities as possible as of that date, with an ongoing commitment to the safety and wellbeing of our students, staff, faculty, and librarians.

Winter Term Update 

We are writing to update you on plans for the winter term and the steps the University of Toronto is taking to balance the learning needs of our students with the need to minimize the spread of COVID-19. The University shifted to a predominantly remote model for learning and work in December to respond to the emergence of the Omicron variant. 

We know that there is uncertainty and apprehension around returning to in-person study and work, and we are relying on expert advice to support our community with enhanced safety measures. We believe that the continuum of education from pre-school through post-secondary is essential to the wellbeing of our society and as the Ontario Science Advisory Table notes, is vital to students’ mental health.  

Our students have told us how important physical presence on campus is to them – both for their academic work and for their mental wellbeing. U of T currently hosts thousands of students in our residences, many of whom have travelled far from home to learn and interact with their professors, classmates and friends. 

For these reasons, in the coming weeks, we will return to more in-person activities on all three U of T campuses.

Return to In-Person Learning

With all of this in mind, we are sharing with you the following plans: 

Effective Monday, February 7, we will increase in-person teaching and activities across all our campuses and Faculties. Exact plans will vary depending on local factors. For example, some undergraduate Faculties will deliver their winter 2022 courses as originally planned, including many in-person sections. The Health Sciences Faculties will work in consultation with their partners in the health and social care systems to increase in-person teaching in a way that supports the health system at a time of great strain. Programs that include placements in settings such as schools may prioritize in-person placements while continuing remote instruction for other elements of their programs. Campuses, divisions, and departments will be reaching out to students and instructors to confirm arrangements, as needed. Students should refer to the information by campus and Faculty available here.  

The Ministry of Colleges and Universities has confirmed that for post-secondary institutions, there are no restrictions on in-person instruction on our campuses, and no distancing or capacity limits for instructional spaces due to the array of public health measures we have successfully implemented on our campuses, including the very high level of compliance with our vaccination mandate.  

We want to acknowledge those staff members who have been working in-person on our campuses throughout the pandemic, including caretakers, lab technicians, library and residence staff, grounds and maintenance staff, and campus safety services. Employees currently working remotely should be ready to return to campus as of Monday, February 7 to support increased in-person teaching and learning and related activities. Staff will be contacted by their managers to discuss specific return-to-campus plans.Alternative work arrangements will need to be in place beyond February 7 for staff roles that have approval to work in any hybrid capacity - i.e., employees with approval to work any portion of the work week remotely. Faculty members and librarians should contact their Dean, Chair, Director or Supervisor to discuss their workload assignment if applicable. 

All employees are expected to be within commuting distance of their workplace, unless approval is obtained in advance to work outside of Ontario. We continue to encourage flexibility and support for employees with childcare responsibilities resulting from potential cancellations of in-person classes for school-age children or day care closures. 

Enhanced Safety Measures

The University of Toronto is closely monitoring the latest public health guidance and continues to update the 12 ways to ensure our campuses provide a safe place in which members of the U of T community can study, learn and work. 

Everyone must wear masks in indoor spaces at the University. Evidence points to the increased efficacy of medical masks. The University is working to make the appropriate masks available, as supplies allow, to U of T community members who are unable to obtain them due to cost or supply chain issues. More information will be available in the coming days at the UTogether site

The University has a limited supply of rapid screening kits at this time and we are prioritizing their use for higher-risk situations. We encourage those community members who are registered in U of T’s rapid screening program to continue uploading their results into UCheck

All students with on-campus activities and all employees, whether or not they are immediately required on campus, must upload proof of vaccination to UCheck as required by the Council of Ontario Medical Officers of Health. Almost 110,000 people have uploaded their vaccine information into UCheck. We are pleased that 99% of our community members are fully vaccinated, with the majority of those remaining on their way to full vaccination.  Members of the community continue to be required to complete the UCheck self-screening and have a green screen before coming to any U of T location.

In addition, UCheck is being updated the week of January 31 to allow you to voluntarily upload documentation related to additional (booster) doses. We encourage everyone to receive an additional vaccination (booster) dose as they become eligible. More appointments are added to the provincial portal and local pharmacies daily. For those without an Ontario health card, appointments are available at the Discovery Pharmacy in the Leslie Dan Faculty of Pharmacy. 

Divisions will make non-classroom spaces available to students to support studying and eating between classes in a distanced fashion. Robarts and Gerstein Libraries on the St. George campus are open to members of the U of T community, as are the UTM Library and UTSC Library. Other campus libraries are open as well, and information can be found here. Operations staff on each campus will be working with divisions to find ways to address this need.  

As we plan for an increasingly vibrant in-person experience for our students, we want to reiterate our commitment to doing all we can to provide safe conditions for working and studying at our campuses. We remain vigilant about evolving public health conditions and continue to adjust and adapt our plans based on the guidance of our community of experts. We look forward to seeing you soon.   


We appreciate the stress that these rapidly changing circumstances may have on members of our community. We encourage anyone who needs support to please reach out for assistance. 

U of T’s My Student Support Program (My SSP) provides students with real-time and/or appointment-based confidential, 24-hour support for any school, health, or general life concern at no cost. 

The Employee & Family Assistance Program (EFAP) is available to employees of the University of Toronto. This program is provided at no cost 24/7 and 365 days a year. Call toll free 1-800-663-1142.

Limiting the Spread of COVID-19 Omicron Variant: Immediate Steps

As many of you are aware, the federal and provincial governments have made a series of announcements regarding efforts to mitigate the spread of COVID-19 in light of the new Omicron variant of concern. All Ontarians are being asked to assist with limiting spread by reducing the number of social gatherings, obtaining their third dose when eligible, and allowing employees to work from home where possible. As we have learned throughout the pandemic, we all have a role to play as individuals and as a University community to support public health in our communities. It is equally important to remember that we have experienced much uncertainty in the recent past and we have relied on expert advice, flexibility, and innovation to continue delivering on our academic mission. 

As a result of recent government announcements, we are implementing some changes beginning tomorrow.

Classes and Exams

Effective tomorrow, December 16, 2021, in-person exams will not be proceeding. 

Online tests and exams will proceed as planned. Campuses and divisions will be reaching out to students and instructors to confirm arrangements for each course that had planned in-person tests and exams. Exams may be modified to another delivery mode or cancelled. 

Most classes will resume on Monday, January 10, 2022 (with some beginning earlier).However, in-person learning for all courses – graduate and undergraduate – will be delayed until Monday, January 31, 2022 (with the exception of some in-person practica, as well as courses in the health sciences, which will resume as planned). Again, campuses, divisions, and departments will be reaching out to students and instructors to confirm arrangements. 

All members of the U of T community must still upload proof of vaccination to UCheck if attending campus for any reason in the winter term.

Working Remotely

With the latest provincial announcement, all employees should work remotely until Monday, January 31, 2022, with the exception of those who must work on campus, such as employees who support operations, construction, and ancillary services, who provide in-person student support, or who are needed for specific in-person research activities.

Alternative work arrangements will need to be in place beyond January 31 for staff roles in any hybrid capacity - i.e., employees planning to work any portion of the work week remotely. 

Regardless of whether roles are required on campus or can work remotely, all employees must upload proof of vaccination to UCheck. All employees are expected to be working near their campus, unless approval is obtained in advance to work outside of Ontario.

Outbound Travel

The federal government has issued a global travel advisory advising Canadians to avoid non-essential travel outside of Canada. Individuals who may be required to travel for work-related reasons should confirm existing travel restrictions including travel advisories, flight availability, and local border restrictions which may prohibit entry to the destination country. In addition, travellers must be fully vaccinated by completing a COVID-19 vaccine series in Canada at least 14 days before travelling.

Travellers are encouraged to review resources available to the University community through International SOS as part of their pre-departure processes. We will be in touch as needed with students engaged in learning abroad in January 2022.

Inbound Travel

Inbound travel is also subject to additional restrictions, including preventing entry to foreign nationals who have been in specific countries for 14 days prior to entry. Canadian citizens and permanent residents who have been to these countries will be subject to enhanced testing, screening, and quarantine measures upon re-entry to Canada.

Until January 14, 2022, those travelling to Canada who are not fully vaccinated with a Health Canada or WHO vaccine may be permitted to enter but will be required to quarantine for 14 days.

Effective January 15, 2022, all foreign nationals must be fully vaccinated in order to enter Canada. This includes international students over the age of 18 and temporary foreign workers with valid work permits. Foreign nationals who are not fully vaccinated will be prohibited from entering Canada unless they fall under one of the limited exemptions including some children under the age of 18, new permanent residents, and agricultural workers. Exempt unvaccinated travellers will continue to be subject to testing, quarantine, and other entry requirements. 

Residences, Sports & Recreation

Residences currently scheduled to be open over the winter break will remain open. All residences will be open as scheduled in January.  Students that choose to leave campus, should take, at minimum, essential items to continue their education, including laptops, textbooks, and important papers. 

For details regarding on-campus student services, including sports and recreation, please visit the websites of U of T Sport & Recreation, Hart House, St. George Student Life, UTM Student Services, and UTSC Student Services.

Some libraries will remain open with limited hours over the holiday break to ensure students have access to the internet and computers as well as access to print research collections. For details on operating hours, please visit the University of Toronto Libraries website.

We appreciate the stress that these rapidly changing circumstances may have on members of our community. We will continue to update you with information to support your current activities and decisions about winter plans.

Greetings and Happy Holiday’s All

The University of Toronto Scarborough will be closing at 5:00 PM on Tuesday, December 21st, 2021, re-opening Monday, January 3rd, 2022 at 8 AM. During this period, the following points should be taken into account:

  • For personal safety reasons, faculty, staff and students entering (and leaving) the buildings are asked to do so through the Main Entrance (Science Wing) and to advise Campus Safety of their presence. All other main entrance doors will be locked over this time frame. Unauthorized persons will be denied entry. Studying on campus over the holiday period will not be permitted.  Those with fob access will be able to continue to use them over the holidays for controlled access. 

  • There will be limited cleaning staff on duty during the holiday closing. Departments requiring caretaking services during this period must make prior arrangements with Facilities Management through Diego Lupallier – Manager, Grounds and Caretaking Operations - (email at Costs will be charged to the requesting department at overtime rates. Such arrangements should be made no later than close of business, December 17, 2021

Facilities Management would also like to take this opportunity to wish you all a Holiday Season filled with peace, joy and love, and the very best for 2022 especially and more than ever in these very unique and challenging times.

As we welcome our community to a new academic year, we have planned for a fall term with expanded in-person experience and have put in place measures that protect and promote safety in our working and learning environment.

Further to last week’s COVID-19 fall planning update, we are providing you with additional details on the latest announcement from the Ministry of Colleges and Universities, proof of vaccination, and the UCheck platform.

Read more to find out about NEW CAMPUS POLICIES regarding accessing the campus in-person.

We look forward to welcoming our community to our campuses and we are writing to provide you with additional information about fall planning. We have been working diligently with the U of T community, public health experts and others for a safe return.

As has been evident through the course of the pandemic, the situation evolves, often rapidly. Given the changing public health landscape, you will be receiving weekly updates on return-to-campus plans.

Read more to find out about NEW CAMPUS POLICIES regarding accessing the campus in-person.

As it prepares for a safe return to campus this fall, the University of Toronto has announced a vaccination requirement and implemented a comprehensive 12-step plan for students, staff, faculty and librarians that is informed by the latest public health guidance.

U of T will require all those intending to be on campus be fully vaccinated – as vaccines have proven to be one of the most effective ways to minimize the dangers of COVID-19.

Whether you are new to UTSC or returning to campus this Fall, we are excited to welcome you. It has been an extraordinary time, and while the past year has brought important and creative learnings about online technologies, we have missed the in-person experience that is a hallmark of the UTSC community. 

Our Summer 2021 courses are being held primarily online, with the exception of some essential elements that cannot be completed virtually, such as laboratories. The campus continues to be open to enable access to computers and study space.

Reflecting recent messaging from the President of the University of Toronto, we are projecting a much richer array of in-person offerings over the course of the 2021-2022 academic year, while also recognizing the need to take into account local circumstances on each of the University of Toronto’s three campuses.

UTSC is planning for a transitional Fall term, which will include an expanded array of in-person options, as well as a robust set of remote options. Our plans are focusing on how best to use our campus spaces to offer rich in-person elements, balancing that with a range of offerings that can be completed fully online. In addition, we want to maximize other on-campus activities such as availability of study space, library resources, in-person learning supports, and offerings from Student Experience and Well-Being.

In the Fall term, approximately 20% of our typical academic activities (classes, labs, tutorials) will available in person. For most A- and B-level courses, there will be a small in-person lecture section and a parallel section offering remote access. Some small upper-level classes will offer an in-person section only. The timetable for courses is available online [Include link to timetable], and it explains which classes and which sections of classes will be in person and which will be remote, either synchronous (“real time”) or asynchronous (recorded for later viewing) this Fall.

Room capacities (as of early July) are set to maintain 2 m distance between students, with a maximum number per classroom of 50. These numbers may be relaxed if public health guidelines allow larger gathering limits indoors.

Courses and sections of courses which are offered remotely will be maintained through the Fall term. If public health guidelines permit, instructors will be able to allow more students into a classroom than are currently registered in the in-person section, but the remote section(s) will not be closed. We plan to have an increased presence of student-facing services on campus this Fall, with an expectation that all services and spaces will be fully in-person for the Winter term.

Students moving into residence are expected to have their first dose of the vaccine prior to move-in day. Anyone who is unable to do so will have 14 days following their move-in date to get vaccinated. At this time, there is not a requirement for non-residence students, faculty or staff to be vaccinated, although this is strongly encouraged.

It is taking careful and creative thought to maximize the opportunities offered by both remote and in-person modalities to create the best possible experiences for students, within the limitations imposed by gathering limits and distancing requirements. Our priority, above all, is the health and well-being of our campus community. In light of vaccination timelines, we expect that we will have fewer constraints in place by the Winter 2022 semester starting in January; to that end, we are planning a substantially  in-person semester, though we will continue to be guided by Public Health requirements.


We are looking forward to welcoming you to UTSC for the 2021-22 academic year!

At UTSC, we are planning a phased approach to restarting on-campus academic activities. We will be offering a mixture of in-person and online courses in the Fall term, and we expect a full return to primarily in-person learning in the Winter term.

In the Fall of 2021, most A- and B-level courses will offer some in-person activities with small numbers of students. These may include an in-person lecture section with restricted enrollment and a parallel section offering remote access, or online lectures with some in-person practical or tutorial groups. As well, some small upper-level classes will offer an in-person section only. 

In order to maintain continuity during the Fall term, courses and sections of courses which are offered remotely will be maintained as remote learning sections throughout the Fall term. If public health guidelines permit, instructors will be able to allow more students in the classroom than are currently registered in the in-person section, but the remote section(s) will not be closed.

Please continue to check this site regularly through the Summer for updates.


General Safety & Physical Distancing Measures

  • Any individual in an indoor space at U of T (that is normally publicly accessible) will be required to wear a face mask or face covering, when measures such as physical barriers are not available. This includes hallways, lobbies, elevators and other common use facilities.
  • Exemptions are provided for people with underlying medical conditions that inhibit their ability to wear masks and individuals in specific areas that are not intended for public use.
  • Masks may be removed when taking part in athletic or fitness activities and in situations where wearing a mask impedes delivery and receiving of services.


  • Physical distancing measures are in place for all non-instructional indoor spaces such as designated eating areas.
  • Physical distancing and capacity limits do not apply to academic instructional spaces such as lecture halls, labs and study areas.

Dedicated entrances and exits are currently being established to promote a one-way flow of traffic to adhere to physical distancing restrictions.

Keep an eye out for signage located across the campus that will encourage and instruct everyone to practice safe physical distancing and proper hand hygiene.

Signage will be provided indicating maximum occupancy for meeting rooms and elevators, as well as to direct the flow of foot traffic.

  • Libraries and classrooms will be cleaned five times per week, while surfaces that people frequently come into contact with--including elevator buttons and doorknobs--will be disinfected twice a day, in keeping with Public Health Ontario guidelines.
  • Caretaking staff are also using a new, chlorine-based solution approved for use against SARS-CoV-2, (the virus that caused COVID-19).

The university will install upwards of 1,000 hand sanitizer and sanitizing wipe dispensers across the three campuses so that people can easily disinfect their hands. Each dispenser will be touchless and installed at an accessible height in visible locations.

  • The University’s vaccination requirement stipulates that all those intending on coming to campus must be fully vaccinated against COVID-19 and must provide proof of vaccination by uploading vaccine receipts to UCheck.
  • UCheck Ambassadors are student staff that will be patrolling high traffic areas on campus, reminding the community to complete the UCheck self-screening. If approached, please show your “Green Screen” and remember these are your peers working hard to ensure a safe campus for all.
  • QR codes used for contact tracing purposes will be posted in common areas across campus including study spaces, computer labs and in the library. Please scan these QR codes with your mobile device whenever you come across them. UTSC staff may be monitoring for compliance.  
  • Environmental Health & Safety (EHS) is conducting assessments across U of T’s three campuses to ensure that adequate physical distancing measures are in place.
  • In high-traffic areas where maintaining a two-metre distance from others isn’t possible or is impractical are being assessed and appropriate protective measures such as Plexiglass barriers and sneeze guards will be installed.
  • All centralized heating, ventilation & air conditioning (HVAC) system filters have been replaced with enhanced MERV 14 filters.
