Montreal, Quebec, Canada

Across the Ottowa River from the city of Ottowa is the Province of Quebec (pronounced Kebec) which has a population of eight million people.  It is the only province in Canada that is predominantly French speaking and has French as it’s official language.  The largest city Is Montreal with a population of 1.65 million people. 

And guess what – yet another Notre Dame Basilica, but instead of going there, here's St. Catherine's Cathedral

The reason I go to this one is because directly BELOW it is a shopping center.

that is directly accessible by their subway system

There are 19 miles of shopping malls underneath the buildings in downtown Montreal.  People can take the subway to go shopping or to their places of employment and never go outside in the cold weather.  The portion that is below St. Catherine's church was excavated AFTER the church was built.  By placing the church itself up on pillars they dug out underneath it to connect it to the other basements that were already in place.  It was considered a major engineering fete.
