Canada's founding father everyone...
Sir John A Macdonald was the first prime minister of canada, and was one of the driving forces of confederation.
He was also a drunk, often going on massive binges and, even for the time, extremely racist, this is the guy behind the residential schools, the Chinese head tax, and a number of other 'fun' policies.
Oh and he was PM for the first railroad across Canada (indeed his second government fell because of a corruption scandal involving the construction of the canadian pacific railway)
He is Canada's second longest serving prime minister (yes he was reelected four years after the aforementioned corruption scandal) only beaten by William Lyon Mackenzie King, Canada's Deppression/wartime PM and guy who talks to ghosts to make policy decisions.
What can I say, we like our crazy prime ministers
EDIT: at this point i should say he is extremely controversial in canada as you can see lol
