My Girlfriend Who Lives in Canada is a song from Avenue Q.
Rod sings this at the wedding of Christmas Eve and Brian when Nicky says Rod is gay. It mentions a girlfriend named Alberta in Vancouver who "cooks like an oven and sucks like a hoover", who once was about to visit but didn't as she had the flu. He ends it with "And I can't wait to eat her pussy again!" Afterwards, Rod makes it clear that Nicky isn't welcome in their apartment anymore.
