French-language learning
This is a French-language school, rather than an English school’s French immersion stream. Families should review MonAvenir’s French-language admission process and current attendance area.
Secondary program choices
The board lists the IB and a health-and-wellness SHSM. The campus includes Grades 7 and 8, while this guide uses the separate secondary academic result.
BEFORE YOU CHOOSE A HOME
Check the address.
Confirm the program.
A nearby home or a shared municipality does not guarantee a place. Ask the board about attendance boundaries and the school about any separate entry requirements.
