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.

Underground "malls" like Toronto's PATH and Montréal's RÉSO were a somewhat obvious urban solution to inclement weather. But they are often criticized for sucking life underground and making the streets at grade feel dead.

When I've toured my American friends through Toronto's CBD in the past, I've heard comments like, "How come you have no retail downtown? It feels dead." And then I have to cheekily say, "Oh, well, we actually have tons of it, we just decided to hide it all underground so it's harder to find and confusing to navigate."

The way you start to counteract these negatives — lack of street life and challenging wayfinding — is to do what Sid Lee Architecture did masterfully here at Place Ville Marie. To the extent possible, you make grade and below grade feel like one space.

Yesterday morning, I took the train from Toronto to Montréal. I'm here for one night for a few meetings. I love trains. You can show up right before departure, the seats are more spacious, and they go downtown to downtown. Plus, there's something romantic to me about whizzing through the landscape. But currently, this trip takes just over 5 hours once you factor in the above stops (see cover photo). That's too long in this day and age, so Canada is, as I understand it, working on a new high-speed rail solution called Alto.

The first phase will connect Ottawa to Montréal (construction is expected to start in 2029), and a subsequent phase will connect Ottawa to Toronto. The top speed will be around 300 km/h, which I'm guessing will result in an effective speed closer to 200 km/h when you factor in stops and any speed limits required near urban centers. With this, the goal is to bring the journey from Toronto to Montréal down to around 3 hours.

One thing to keep in mind is that Ottawa does not lie on the fastest route between Toronto and Montréal; it adds about 70 km. But it's of course necessary. In theory, an express route with no stops running TGV or Shinkansen-like trains could bring the journey time down closer to 2 hours. But that's not what is being planned from what I have read. Regardless, 3 hours is still a big deal and a meaningful improvement. It makes the trip faster than flying, and certainly faster than driving.

Could current drive times ultimately change with autonomous vehicles? Maybe, but it's unlikely to be by this much. I hate long road trips and the same would be true even if a robot were driving me. So I look forward to one day — in my 50s? — doing this journey in 3 hours. If we could get it down to 2 hours and change, that much better. That's a trip worth taking for a night out or just to stock up on bagels.
