I don't know if this is Canadian but it's for a toilet tissue - a little boy sets up rolls of TP around the house and then feeds his little golden retriever pup. The little pup runs like mad for his food but starts sliding around as he is too awkward to negotiate turns. Of course, he slides into the TP so all is well.

A similar commercial has the boy placing TP rolls on either side of the car so when the pup slides back and forth, he's got cushioning.

More dogs in ads, I say!
