Fellow Winnipeger here! I remember driving by that sign as a kid and being baffled by that word.
I stayed in the Ottawa Jail Hostel in the former Carleton County Gaol. The receptionist sure acted like a warden.
Canada is not just english-speaking, but also french speaking. We have TWO national languages, with equal importance.
This being said, I would suspect the english word gaol comes from the french word geôle.
