Any apps sent now will be returned, so no point in even trying this.
Program should open up again Monday January 4, 2016. Based on this year's cap being reached in a day and a half... it's pretty much a given next year CIC will receive well over 5000 applications on January 4.
I think they will switch to some kind of lottery system for all apps that arrive in the first day or 2, else anyone doing same-day delivery service who is local to Mississauga will be able to be first in line, and people sending apps from out West basically won't have a chance.
