Best place to shop is Canadian Plane Trade which is part of the COPA newspaper and available online for members. Barnstormers web site is also good and lots of Canadian planes in there too. I suggest you join COPA when you get here just to get the monthly newspaper. COPA's places to fly lists all sorts of airports and strips in Canada.

Consider carefully if you wish to go with a Basic Ultralight. With an old tail dragger registered as an ultralight, there are zero bureaucratic hassles. The category is pretty generous. You sign your own medical declaration and declare yourself fit

. You are not subject to the mood swings of your aircraft mechanic. It is a very low dollar solution with a few limitations:
Max gross weight 1200 lbs.
Maximum stall speed: 45 mph
Big one: no unlicensed passengers.

My old Taylorcraft fits the basic UL category. I still fly into class D airports without a transponder no problem.
I live in Norfolk county about 1.5 hours from toronto by car. hangar rent around here is about $100-150/month for a rural small airfield. There are 5 within 20 minutes of my house. If you get away from the Greater Toronto area, you will find Southern Ontario to be very friendly to tail draggers.
