In Ontario, he'd be served with a human rights complaint. Chances are here, people would:
a) seek to destroy him
b) seek defamation charges against him
c) somehow try and indict him for inciting hate crimes
d) denounce him
In Toronto, for our upcoming mayoral election, we're set to:
a) elect a MtF city councilor (she came in 3rd for mayor in a recent election, I just can't recall if it was the most recent one or not)
b) elect an openly gay mayor (our former provincial minister of health, who was openly gay at the time of his election)
In fact, I don't think any media outlet whatsoever has mentioned their identities/orientations in any way, except maybe to proclaim that social progress is continually being made. The candidates pick at each other for policies, and never venture into questionable territory such as LGBT issues. Most Ontarians see this as a no-go, and we see that as a very good reason NOT to elect someone.
Point is, we like to elect people for their policies and ability to manage fiscal and social policies, not for their identity. Generally, those who voice strong religious beliefs (which disparage others) are promptly voted out. Hell, even our federal conservative government has stated it would not try and retract gay marriage legislation, even if they were to attain a majority government (even they realize that members of all walks of life like to vote for fiscal conservatism, but not social conservatism).
What's my political experience with Michigan, you ask? I can almost see Michigan from my window!

I'm in London now, so that's somewhat truthful-ish...
