When is the deadline for university applications?

I live in Aurora, ON, Canada.

AND IF UNDER THE REQUIREMENTS IT LISTS ADDITIONAL REQUIREMENTS (i.e. "Non-academic requirements", like essays), are those extra requirements due the same date as the applications?!

I know I should know all this by now, but it’s a long story.

if you are a 12th grader it will due the beginning of next year probably february march around there. everything is due the same day.
