I was just thinking that one of the states should be called Washington (especially since there is already a Jefferson). Other Presidents (since the PoD) are: Crawford, Clay, Hamilton Jr., Calhoun, Brandon, Yates, Haines, Lee, and Hawthorne (though the likelihood of HIM getting a state named after him is pretty unlikely).
Victoria was founded in 1846 OTL, so that is easy enough to butterfly away. As for where a purpose-built *Canadian capital would be located....the Great Lakes sounds cool, but I wonder if there would be a fear of American attack? I'm definitely open to suggestion, as I only know some basics about Canadian geography.
