Sorry about the late response Duck!
Look at the Canadian border in the Straits and anywhere you find a plateau/structure is a great place to start looking. and don't overlook Constance Bank southwest of Victoria.
Here's the word right from the horses mouth on entering Canadian waters for fishing:
IMPORTANT NEW POLICY FOR FISHING/ENTERING CANADIAN WATERSAll the speculation and confusion has finally been addressed and officially answered, you can read the ENTIRE bulletin
http://www.cbsa-asfc.gc.ca/media/facts-faits/096-eng.htmlThe Canadian gov't has made an exception for anglers and private boaters who enter Canadian water (without landing, swimming, tying to another vessel, etc), allowing them to call in via cell phone when entering Canadian water
1-888-226-7277For the purpose of calling into U.S. Customs Border Protection when retuning to U.S., here is clarification of
U.S. Policy from Chief CBP Officer Ronald G. Smith, Public Affairs Liaison"U.S. boaters who go into Canadian waters with the sole purpose of fishing, there is no requirement to call US CBP upon returning to the U.S. If the boater does any other activity, swimming, ties up to another boat, docks, goes ashore, anything other than just fishing and they check in with CBSA on the Canadian side then they will need to re-enter the U.S. by calling CBP. At that time they will need appropriate documents, Passport, Passport Card, Enhanced Driver’s License, NEXUS card etc".Ronald G Smith
