"For all applications: If the application is submitted using a courier service instead of by mail, use this address instead (no public drop-offs): Caseit should have been sent to Sydney. The checklist indicating to send to Mississauga was an error. They have since updated the checklist again saying Sydney. Good luck and hopefully they don't sent back because of their error
Processing Centre - Mississauga, 2 Robert Speck Parkway, Suite 300, Mississauga, Ontario, L4Z 1H8"
That's exactly what my checklist says. Hopefully, they will not send back as its an error on their part.
