Thanks all for the recommendations, please keep them coming. I am publishing them as a PDF because they do not fit anymore in a single post.
For Vancouver Island - Tanks and Sorb can be easily obtained through Deep Fathoms - Bill Nadeau was national director for IANTD. He can also do fills. Bill I believe largely trains on the AP, there is a SF2 crowd over in Vancouver. Sorb can also be obtained in Vancouver very easily, as most will fly in there and likely take the ferry over to Vancouver Island (2 hour ferry, drive on/off, nice views on the way over).
There is also a great GUE crowd who are pretty easy going. Drop in dives in Victoria, however unsure how the crowd is for other rebreather divers outside of GUE, but they do allow non-GUE for drop-in recreational dives, so maybe there are a few interested. Check Jason Cook Diving.
Campbell River (Oceanfix.ca) has a good boat and regularly hosts rebreather divers for trips. There is a good local AP crowd from Nanaimo north. North of Campbell River is kind of remote, unsure how rebreather divers are handled on charters, however the diving up there is very nice wall dives. Unsure about the crowd other than the GUE team south of Nanaimo, appologies.
Highly recommend: SS Capilano, SS Gulf Stream. Good wall dives near Campbell River. Nanaimo has VERY accessible shore diving.
Note that all VI diving is pretty chilly. 6-10*C. Dress warm
