Looking for pet friendly venues in ontario

Hey there,
So we just got engaged and we haven't decided on a location. But we have talked about having our dog at the wedding since basically forever. Thus I decided to attempt to look for a location/venue based on that. At least as a starting point.
I have found a service based in Toronto that will bring our pup for photos and to the ceremony and what not. I'm just not sure if just any venue will accept or allow a dog to come in.
Any ideas? Experiences? Or advice would be much appreciated.
THANKS Beth
