Katts and Dog is a Canadian production. Like almost all Canadian productions, it is co-produced with another country, in this case France. This is done to join costs to make a more attractive show, a show that will attract viewers from all over the world. The french character on the show was not to show the Quebec/Ontario relations (although it does a nice job).
The character was there to represent the production with France. The characters and the show itself are created in a neutral manner. The people in many countries can relate to the characters and the setting because there is no real connection to a particular city. Canadians can relate as Canadians, and the rest of the world can relate as well.
