6 hr Montreal Layover
 

So, my family and I are travelling from St. Johns to Vancouver in July and will have a ~6 hr layover in Montreal. I was wondering if there is anything worth venturing out of the airport for, or if we'd be better off just sitting idle. None of us have ever been to Montreal, so we'd like to check out a local cafe or something if possible.

The Old Montreal and beautiful Notre-Dame Basilica are definitely worth
seeing.
