Practical
Language, transit, and the early alarm
Street signs, menus in neighbourhood restaurants, and transit announcements are French first. Hotel staff in the central districts switch to English as a normal part of the job, which is enough for arrival, breakfast, and a problem with a key. It is still worth knowing bonjour and merci, because the city is not performing English for you outside the lobby. If you need a pharmacy or a transit question on the sidewalk, a polite French opening helps.
The metro and buses cover the island well enough for a neighbourhood stay, and a car is often a burden downtown in summer construction and winter snow. Rules on parking change by borough. Read them before you arrive with a vehicle you do not need. For YUL, leave a margin in both directions and do not assume yesterday's transfer time still holds after a storm. This guide does not quote fares or room charges.
