If you look on a map --
-- you will see that the part of Canada directly north of where most of the outdoor sets of this movie were filmed (US Southwest) is Vancouver.
Not Scarborough (Toronto), Ontario. Or "Scarberia" as it is more appropriately known.
So why didn't they do the studio work in Vancouver instead of Toronto?
Why is it that when Matthew Perry is in a movie that is partly filmed in Canada, it always has to be in Southern Ontario, and mostly Toronto, specifically? Just because Mr. Perry grew up in Ottawa?
