How quickly do you need them to be ready for a significant role?
If immediately, you don't have many options besides Mighty Cavanagh and Timmy Westbrook. Maybe Frederique.
Somewhat near future, you have more options. Guys like Davis Wayne Newton, Frankie Dee, Sayeed Ali, and Mimic. All start with some popularity in Canada.
Long term, well you have too many options to name. But, the two guys I think are the best workers not in a major company are Nelson Callum and Mr Lucha III. You have will have to ask Mr. Lucha to work in Canada, but he is wonderful.
Of course all of this depends on whose contracts have expired in that time. I know it is a sorta open ended answer, but hard to get too specific, since every game is a bit different.
