renfrew was traditionally Liberal in its politics, thoguh socially very Conservative. There are substantial Polish settlements (see Barry's Bay), also a large military contingent (but that vote has shifted Tory now) and civil servants (?) living in Deep River (nuclear workers?)
Isn't/wasn't Renfrew quite Catholic, explaining its old Liberal lean?
Deep River voted Liberal in 2006, not sure about last year. Probably Tory - after all, it was the strongest Tory riding in Ontario IIRC.
In 2001 Census, 45.2% Catholic and Protestant 43%. Religion is only asked each ten years.
