"Missing middle" construction seems inefficient for heating and Montreal gets cold. It probably helped for cooling in the summer before A/C existed, but compared with here in the midwest (not even anywhere south) Us, Montreal doesn't really get that hot. "Missing middle" is a style I'd expect more in Mediterranean climates, like southern California.
It's also not as good is insulating for things like sound. Maybe that's a cultural difference. What part of France were a lot of the immigrants to Montreal originally from?
