Their economy is a lot more buoyant than ours, and never actually went into recession. When I was out there (2011) I was able to find waitressing jobs paying $18-20ph + tips without too much difficulty. You do still have to look - jobs won't come and find you - but they are much more abundant than the UK if you have some form of experience.

Where in Ontario would you be?
You do realize that Ontario is a province (8 times the size of England!) and not a city, so your study abroad experience would depend massively depending on where you are; e.g. a semester abroad in Toronto (the 4th largest city in North America) would be incredibly different to a semester in London, Thunder Bay, Waterloo, etc. (smaller towns)
