For any interested in Canadian courses, I came across this rather extensive list of abandoned speedways... lots of short-track ovals it seems:

There's also Riverview near Thunder Bay:

You can soon add the speedway at Mosport/Canadian Tire Motorsport Park, which is now done and will be re-developed into part of the Driver Development Track I believe.
A few other shuttered ones listed on the 'pedia... Edenvale airport would be the closest road course to me I think.

Sorry about the lack of photos... but many are linked from that first set of speedways. I should go exploring.
