Is Simcoe,Ont. a good city to live in ?

(First answer! Wahoo!!)

Any city that is "immigrant-free" would be a total waste of space. ...Incredibly irrelevant and boring.

But, since Simcoe, Ontario, is such a tiny, tiny little place, there's a good chance the percentage of visible minorities (if that's what you REALLY mean by "immigrants") is low. Small towns are like that. (Every human being in Canada is technically an "immigrant", since humans didn't evolve on this continent.)

From what I know of people in that area, your apparent racist views won't be welcomed. Better to go live in the southern U.S., and join the Klan or the Aryan Nations or something. Oh...but then you'd be an immigrant, and they wouldn't want you, anyway.

Better place to visit, not to live.
It's too small.

it's not a city, it's a very nice town, Canada is built on immigration, how can it be immigrant free ?..

No, you have to travel from Niagara Falls, New York to Niagara Falls, Ontario to visit.
