I'm not aware of any sailing schools up there but if there are any they should show up with google. I would suggest you try contacting the local yacht clubs (gibsonsyachtclub.com or gulfyachtclub.com). If they don't know of anyone who will take you out for the day, you might want to ask if they have any weeknight racing which you could volunteer to crew for.
My yacht club in Victoria has a yellow box painted on the asphalt at the top of the dock where people who want to crew can go. Skippers will usually go by and ask about experience and let you on if they are short handed. Its a bit of a trial by fire way of learning to sail, but racing can be really exhilerating (or really boring if there isn't any wind). It doesn't take much other than elbow greast to "grind" or "tail" (Grinding is turning the winches, tailing is pulling on the line while the grinder turns the winches.)
If you do end up racing just remember two things: its not called rope on a boat....its called "line"....and when someone says "Duck!" they aren't referring to waterfowl, they are referring to the boom coming across - usually with little regard for any heads that are in the way!)
Best of luck.
