Well, from the responses of those lucky Canadians who have already received their copy of Monsters Inc., the consensus seems to be that it is missing the "Isolated Sound Effects Track" in favour of the French audio track. All of the other extras are identical.
Other than French audio tracks and more recently Bilingual covers, Canadian and US Region 1 DVDs are usually identical. I was quite surprised that the sound effects track was omitted. Whether that remains true when I receive my copy next week remains to be seen - I certainly hope not!
