You can apply for a "Sister Local Status" transfer into Local 891, which will put you ahead of many hundreds (probably thousands) of Permitees.

There's a second film Union in Vancouver, the ACFC. It's got somewhat of a lock on the low budget stuff. Guys aren't supposed to work ACFC gigs if they're IA.....but the reality is that a great many do (gotta eat).

Vancouver was at one time able to field around 20+ full motion picture crews at once (as in all in one day). Those were some pretty flush times up here, but they're somewhat in the past now. Still lots of work, but much of it is dependent on the Canadian vs U.S. dollar, and what other perks are being offered in various provinces and states in terms of tax breaks, etc.
Your best shot is to work both IA and ACFC gigs, and hope that in the few (or more) years it takes to get to full membership, and get some steady IA work, you can make a somewhat steady work week.
Vancouver is a city unlike any other in North America. You can die of exposure or get attacked by a bear by walking 5 minutes from some of the most expensive homes in North America.
But then you can also sail in the morning, and snow ski that afternoon throughout much of the winter (and still be home for dinner) you can see the ski hill from the deck of your boat, and see the sailboats while sking down "The Cut"........with the snow staying up on the mountains most of the winter, and out of the city (not much snow to speak of in Vancouver City proper).
I.A #891 is one of the largest, best funded, and strong I.A. film locals anywhere in North America. A million bucks cash reserve in the bank, and a large, full time crew of Stewards and administrative support...........once you're in, it's a good place to be........the Local, and the City.
