Every list on GCA inevitably contains American and some courses from the British Isles. I rarely see courses noted outside that group and perhaps these Canadian courses aren't up to the snuff of those listed here. But I figured I'd give a quick list a few of my favourites under $85 CAD (that's like $55 for those who are south of the border, cheaper if you are from the UK even).
Waterton Lakes (Thomson/Thompson - Alberta) - $67
Waskesiu (Thompson - Saskatchewan) - $83
Cooke Municipal (Cooke - Saskatchewan) - $66
Tarandowah (Hawtree - Ontario) - $80
Lakeview (Strong - Ontario) - $82
Grand Mere (Travis/Allison - Quebec) - $76
Just over $100 I would throw a vote behind Kawartha Golf Club (Thompson - Ontario) - $115 peak rate as an unaccompanied guest.
Alex-As the soon to be 51st state there will be more eyes on Canada’s lineup shortly. 
Oddly, I was just thinking about how many of our courses would make the US top 100 if this ever happens. I suspect the "big 8" - Thompson's 5, Toronto, and the two Cabots - would make the cut, but I'm not sure a ninth would sneak in, unless Hamilton reverses the damages inflicted from the recent butchering via Mackenzie and Ebert
