I mean in the end maybe the intent doesn't matter, but should Dundas Ontario & Dundas County change their names?
Maybe? Probably a decision for each of those communities. I don't think that when movements like this happen there needs to be some sort of incontrovertible standard or rigid consistency. If people in Toronto, or their elected officials, decide they want to change the name of a street I don't necessarily think it's then incumbent on people of another community to make the same decision. In a democracy I think to one extent or another people get to make their own choices but, by that same measure, if those people decide not to make changes different people can look at that decision and make conclusions about the people who made it.
This is why slippery slope arguments are so fallacious. As people we're perfectly capable of assessing each situation according to its own merits and coming to separate decisions as we feel they warrant. If people think Henry Dundas was enough of a jerk to warrant not naming things after him, fair enough. That doesn't then require them coming to the same conclusion about anyone else.
