The heat waves in summer are definitely becoming increasingly dangerous to the population of Montreal, especially immigrants and indigenous populations because they have less money and access to resources. The apartments in Montreal are old, built to stay warm during the harsh winters before hot summers were a health risk. In today's world, that means they heat up like an oven when we have several days straight of 100 degree weather, and it's very hard to cool them down.
There isn't much being done yet about the danger of heat waves, as it's a fairly recent problem. An older issue in Montreal is the cold, icy winters, which people muscle their way through by wearing heavy winter coats, ski masks, and "crampons" which you slide onto your boot for extra traction on the slippery streets. The city also adapts by making the long winters more fun. In Parc Mount-Royal, you can go ice skating or sledding, or even ride a horse-drawn sleigh!
