Notices of service interruption include the reason for the disruption, the anticipated duration, a description of alternate facilities or services (if available), as well as accessible routes for making one’s way to these alternate facilities and services. The notice is placed in conspicuous campus locations and, when appropriate, on this site.

The University of Ottawa is proud to offer an inclusive environment to its entire community. We invite you to send us comments and suggestions on accessibility that will help us to keep on improving the level of accessibility campus-wide.  For more information on accessibility at the University of Ottawa, please visit the Accessibility Hub.

The Accessibility for Ontarians with Disabilities Act states that all employers must provide emergency response information in an accessible format to all employees with a disability that requires an accommodation. If an employee has an emergency response plan in place, please ensure that you revisit the emergency response plan with the employee in light of the temporary disruptions/maintenance. If an employee submits a new request for an accommodation due to a disability, the employee should discussion their request with their supervisor and/or the Human Resources Department.

If employees require advice on emergency preparedness or assistance with developing a personal emergency plan, they should inform their supervisor and/or the Human Resources Department. The Emergency Management Office may be consulted should subject matter expertise be required.

Long term interruption notices are mostly due to construction projects on campus.
