Canada has produced some great talents to be sure, but lets be honest It has not produced as many stars as America. I mean how is it "unreal"? It's a freakin country in North America. Mexico has produced it's fair share of star too.
Canada has produced some of the all time greats but historically there are a few states in America like Texas, California, Tennessee. who have produced just as many legends. Lets not get out of context here.
To me the greatest Canadian star has to be Bret Hart, bar none.
Jericho is maybe second Roddy Piper third, Gene Kiniski fourth. and then we can talk Kenny Omega, Edge, Christian, Benoit etc....
But there are several American states who can claim equal lineage and those are just states.
The reason it's unreal is because the population of Canada is much smaller then the United States.
