I'm writing this post from the concourse level of Place Ville Marie Esplanade in Montréal (also known as Galerie PVM) while I wait for my next meeting. Like the PATH in Toronto, the space I'm in is part of an underground network of restaurants, shops, and circulation spaces that runs through downtown Montréal.

But what makes the space I'm in right now particularly noteworthy is that I'm sitting beneath an enormous glass roof supported by 18 glass beams measuring 15 meters long and 0.9 meters tall. So, while I am below grade, I have a clear view of The Ring, Mont-Royal, and the street life happening above me.

A few years ago, I was touring a friend from the US around Toronto’s Financial District and the first thing he said to me was: “You have no retail.” And that’s certainly what it might look like at first glance.

But there’s actually lots of retail. It’s just all underground in an over 30 kilometer long network of walkways called the PATH.

Initially conceived of as the antidote to Canadian winters, “underground cities” are a kind of uniquely Canadian form of urbanism. Toronto and Montreal have the largest ones in the world and they continue to grow. As new towers are built, new connections are added.

But the downside to all of this is that it pulls street life down underground. And it can conceal a lot of the urban vibrancy that is actually take place. So maybe we need to come up with design solutions to better connect these subterranean cities back to street level and also not forget about the street.

I’m thinking about this today because of a CBC documentary I watched this morning called Life Below Zero. It basically argues that – unlike other cold climate cities and countries – the vast majority of Canadians actually hate winter. And underground cities are our way of trying to ignore it.
