are you looking for a psecific breed of dog ? at the very bottom of every page is a contact us link. that will let you email the owner of this site. i would think he would know if any of them are in your area.
Well, on the first link that was given to me I found a breeder for the type of dog I am looking into, unfortunately he is in Calgary, Alberta...which is across the country. Will also check out the second link as well.
What kind of dog are you looking for? I think there is a book or magazine that lists all the breeders in Canada, and you can then narrow it down to province. I think it comes out by the canadian kennel club. If you can tell me the breed i may be able to help you. You can also goggle the breed and state the province.
I am not in Ottawa, but closer to Toronto, but I know of many people who will travel if they find something
