In 2026, you generally do not need a car when visiting Montreal, especially if you are staying in central areas like Old Montreal, Downtown, or the Plateau. Montreal is one of the most walkable cities in North America and boasts an exceptional public transit system operated by the STM. The Montreal Metro is clean, safe, and efficient, connecting all major tourist landmarks and the "Underground City" (RÉSO). Furthermore, Montreal is a world leader in cycling infrastructure; the BIXI bike-share system is ubiquitous and offers an affordable way to navigate the city's extensive "Route Verte" paths. For trips to the airport, the 747 Express Bus runs 24/7, and the newly expanded REM (Réseau express métropolitain) light rail provides high-speed links to the suburbs. Having a car in downtown Montreal can actually be a hindrance due to expensive parking (often $30-$45 per night), complex "no-parking" signs in French, and significant seasonal construction. A car is only recommended if you plan to do day trips to the Laurentian Mountains or the Eastern Townships; otherwise, your feet, the Metro, and the occasional Uber are all you need.
