Academic Calendar

The dates shown in the printable versions of the academic calendars take precedence over those displayed in the tables. During each term of your graduate studies at INRS, you will have a number of important dates to keep in mind to ensure your academic success and help manage your student file.

When June 24 and July 1 fall on a Saturday, each holiday is observed the previous Friday.

The INRS academic calendars do not apply to joint programs in earth sciences (INRS-Université Laval). For these programs, the calendar of the partner university applies.

Contact the Registrar’s Office if you want more information about academic calendars.
