Montreal

The coldest of the four cities in winter, and the one whose whole urban design bends around that fact.

Winter in Montreal

RESO, the underground city

Montreal's RESO network links metro stations, office towers, shopping centres and residential buildings across more than 33 km of indoor, climate-controlled corridors — genuinely useful in a city where the January average sits nearly 9 degrees colder than Toronto's. It's not a novelty; locals commute, shop and eat through it all winter without a coat.

Igloofest

Held in the Old Port from January 15 to February 7, 2026, Igloofest is an outdoor electronic music festival that runs specifically because of the cold, not despite it — dress for genuinely sub-zero standing-around temperatures if you go.

Summer in Montreal

Just for Laughs

The world's largest comedy festival runs July 15–26, 2026, across multiple downtown venues — book specific show tickets ahead, since the festival's biggest names sell out independently of general festival attendance.

Montreal's summer is genuinely warmer and more humid than its winter reputation suggests, with July highs matching or exceeding Toronto's. The city's outdoor terrace culture — restaurant patios spilling onto sidewalks across the Plateau and Mile End — is a real, specifically summer-only feature that mostly disappears by October.

Getting around

The STM metro is the practical winter option — four lines, and much of downtown is reachable without surfacing thanks to RESO connections. In summer, Montreal's BIXI bike-share network becomes a genuinely competitive way to get around the flatter parts of downtown and the Plateau.
