We also did a little wander down by the waterfront and checked out the old expo site. I think the last time my dad was in Montreal he as attending Expo 67... Crazy!
also on a side note... found Montreal's Trudeau airport highly confusing and the airport shuttle very vexing.
This is the altar in Notre Dame Basilica in Montreal. Mom and I ducked in here after wandering around in the morning checking out old Montreal. It was one of the only days that was overcast and rainy. We were just so lucky.
