Off-topic:
According to Wikipedia, it's because there is a "constituent community" of the City of Hamilton near Lake Ontario called Dundas which was a prosperous independent city in the middle of the 19th Century, leading neighboring Hamilton in regional importance. Streets leading from it/to it were named Dundas as a result, including Toronto's Dundas' Street, which used to terminate in Dundas. Dundas was eventually eclipsed and annexed into the City of Hamilton, though I can't find a date for this.
