Hi!
You must mail your application to Mississauga, check this link:
http://www.cic.gc.ca/english/information/offices/canada/mississauga.asp
Vegreville doesnt deal with new applications of Sponsorship. Recently, Mississauga has been stablish as the new processing center for sponsorship applications EVEN IF THEY ARE INLAND. Even those who sent their files since july 2013 have been transfered to Missisauga.
Those still at vegreville are only wainting for DM or had applied before july 2013.
If inside the application you wrote Vegreville, you have to correct it, change it for CPC-Mississauga.
Parrainer votre époux, ou conjoint de fait au Canada:
CTD Mississauga
C.P. 5040, Succ B
Mississauga (Ontario)
L5A 3A4
Missisauga will process your application, and if they have any doubts of the relationship they will transfer your file to a local office in order to get an interview before getting AIP. If they dont have any doubts, then your file will stay in Missisauga until the final DM. Then, it will be transfer to a local office only for you to land. Which is totally normal, and everyone who gets approve will eventually do it.
Just to be clear again: VEGREVILLE DOES NOT PROCESS SPONSORSHIP APPLICATIONS ANYMORE.
Well, good luck!
and God bless!
