Montreal is the second-largest city in Canada and the second-largest predominantly French-speaking city in the western world, after Paris. Language is the most conspicuous difference between this city and province and the rest of Canada, but more on that later. The city’s reputation for lively nightlife and hedonism began during the period of prohibition when Americans would head north in search of alcohol and a good time, and it remains a bustling, cosmopolitan city to this today. It has a more European feel than a standard North American city, as well as a relatively inexpensive cost of living compared with other large Canadian cities. The city takes its name from the three-peaked hill, Mount Royal, which sits immediately northwest of downtown.
I was born, raised and lived in Montréal for the past 25 years. Lots of questions and statements found here could use answers and complementary information.
First, French is a huge part of living in Montréal. It is essential. If, as some might have stated, it would be possible for you to find employment speaking English, those jobs will never be quite interesting. The real challenge about not speaking French would definitely be socialization.
