A mediocre politician at best, with a bunch of lousy kids, but is that reason to rename it? No known scandals, at worst an a-hole father.
Was he instrumental in Ipperwash/Dudley George's murder? Or the Walkerton scandal? Nope. So, please don't make the false equivalency of a meh politician to a man who singlehandedly quashed the immediate abolition of slavery in the British Empire.
