Most students are due to return to classrooms again on Tuesday after returning to online learning for several weeks due to a number of issues, including record-high COVID-19 case counts.

The seven-day average for COVID-19 infections is 856.

Alberta continues to lead Canada for active cases per 1 million population with Manitoba a close second.
