COVID-19 - 2019 Novel Coronavirus

COVID-19: Spaces, Events and Services

U of G is committed to providing a safe environment where our community can study, research, work and live. Custodial Services’ cleaning protocols follow the recommendations of Wellington-Dufferin-Guelph Public Health and government agencies.  

Buildings and Facilities

U of G buildings are open and accessible. If you have concerns about accessibility or need accommodation, please contact the Office of Diversity and Human Rights at

Research Spaces

U of G’s COVID-19 safety measures and practices apply in all research spaces. Learn more on the Research during COVID-19 page.


All centrally booked classrooms in use at U of G have ventilation measures in place that provide for the equivalent of six air changes per hour (ACH). Air movement and air purifiers allow these spaces to reach this ventilation target – a measure equal to the standard in place for medical examination rooms.  A summary of the measurement and assessment results for these classrooms can be found on the Physical Resources website. 

U of G is adjusting mechanical systems to ensure they continue running at high-quality standards. We are maximizing the flow of outside air into all campus buildings and are purging the air in buildings at the start and end of the day.

By upgrading all mixed air handling units to MERV-15 and MERV-16 filters, U of G has exceeded industry recommended standards of MERV-13 filters as set in the ASHRAE Core Recommendations for Reducing Airborne Infectious Aerosol Exposure. Over 92 per cent of classroom air handling units are equipped with MERV-16 filters. 

All centrally booked classrooms in use at U of G have had ventilation measurements and assessments completed through Physical Resources, Maintenance and Energy Services. All assessed spaces have achieved six equivalent air changes per hour either through actual air movement or augmented by air purifiers.

All buildings are running on maximum outside air flow – this includes HVAC units that service offices. Classrooms, seminar spaces and teaching labs were specifically assessed due to the occupant proximity and loading. These spaces run with a minimum threshold of six equivalent air changes per hour. Some spaces are serviced with HEPA (High Efficiency Particulate Air) filtration purifiers.

Classroom air flow devices are being left “open” in order to maintain the same airflow the space had at the time it was assessed and achieved the six equivalent air changes per hour (ACH) standard. Demand control ventilation systems within the digitally controlled spaces have been disabled, and the pneumatic controls in the non-digitally controlled spaces are disabled as well for varying air volumes to maintain the minimum six ACH standard. Measurements were completed with PR’s trades workers and a National Environmental Balancing Bureau certified consultant.

Our standard of six equivalent air exchanges per hour is based on the recommendation for medical examination rooms where there may be infectious aerosols present. The Harvard T.H. Chan School of Public Health recommends at least four air exchanges per hour for continuously occupied classroom spaces.

U of G’s residences are a home away from home for many of our students and an important aspect of community. Visit the Student Housing website for guidelines on living in residence during COVID-19.


In-person events can take place, as long as current safety measures are followed. Many events will provide a hybrid option for those that cannot join. For information on a specific event, contact the event’s organizers. Check the University’s events calendar for more information.

The University of Guelph Events Framework has been paused.

Employee-led, -supervised or -endorsed events
In-person and hybrid meetings are permitted. Event planners should consider whether a hybrid format meets the event goals and is feasible.

Registered Student Organization events

Events planned by Registered Student Organizations (e.g., clubs) must be approved by the Student Events & Risk Management (SE&RM) submission process. Submissions will be reviewed by the University’s SE&RM committee.
