Thanks for sharing your experience with traffic.For those who live within the 404 corridor and whose oath is in Mississauga at 9AM:
I left home at 6:45 and reached by 7:45 ( exactly 1 hour); had time for breakfast before checking in (invitation and ID verification etc.) by 8:30-45
My suggestion is to hit the 401 by 7AM. As you all know five minutes can make a BIG difference during the rush hour.
