Montreal has too many commercial streets for one post, so I'll just do the commercial streets within a 15-minute walk of my home. Like many parts of central Montreal, there is a particularly dense concentration of commercial streets so it's very convenient
Beaubien
A long commercial street with a mix of everyday essentials like grocery stores, bakeries, butchers, etc. as well as lots of bars, cafés and restaurants.

Saint-Zotique
A little more mixed residential/commercial than Beaubien, fairly restaurant heavy, but with a lot of daily essentials like grocery stores too.

Dante
Another mixed residential/commercial street. Most of the businesses are food-related but there's also a famous hardware store. Kind of the spiritual heart of Little Italy.

Saint-Laurent
A real mixed bag. Little Italy. Lots of restaurants, cafés and bars, but also plenty of grocery stores. Attracts a lot of visitors from the suburbs.

Jean-Talon
A major traffic artery, not very pleasant to walk on, but there's a very interesting mix of businesses, with a lot of ethnic grocery stores, spillover from the Jean-Talon Market, and in the west there are music venues, breweries and bars.

Bélanger
An odd duck. Lots of useful shops and restaurants, many of them Latin American, but the street feels neither here nor there.

De Castelnau
A lovely little neighbourhood street that is pedestrianized during the summer months. Feels like the heart of a village.

Saint-Hubert
The big one. Ugly but very lively. Chain stores, quirky independent shops, lots of Latin American businesses, bars, restaurants. Parts are gentrifying quickly but the north end is getting even more immigrant-focused.
