Montreal-shop on Sunday?
 

We're arriving late on a Saturday and departing Monday morning from Montreal, so our only full day there will be a Sunday. Is the underground mall open at all on Sundays? What about other stores? Thanks!

Many if not most stores are open on Sundays; this holds true for the underground mall.

Stores hours are reduced on sunday; most shops and malls are only open from noon to 5. Which underground mall are you talking about, there are a few. You should also hit les Ailes, a wonderful department store right next to the Eaton Centre...

It does depend upon your specific dates. The "underground" is NOT open ALL Sundays. It there's a holiday involved, Canadian or American, all bets are off. In Canada they take all holidays more seriously.

Thanks, everyone!
