No priority immigration in Canada unless you have Nexus. That said, the automated kiosks are said to have reduced wait times though YMMV (potentially lots of international flights from resort destinations coming in that time IIRC). If you have GE, it'll speed up process through U.S. preclearance and maybe security (take your GE card) - the regional FC tcket may get you priority security though never sure how much that is worth - and you may need to go to a check in desk.
