What does a business lawyer in Montréal do?

A Montréal business lawyer handles the legal side of starting, running, and growing a company. That covers incorporating, drafting shareholder agreements and commercial contracts, buying or selling a company, and stepping in when a deal turns into a dispute. A lot of it is preventive work, structuring a venture so problems don't surface later. When a dispute does reach court, it's heard at the Palais de justice de Montréal at 1 rue Notre-Dame Est, in either the Cour supérieure or the Cour du Québec depending on the amount at stake.

Businesses here run from the downtown core out to the West Island, so you'll find firms serving clients in Westmount, Pointe-Claire, Kirkland, Dorval, and Dollard-Des Ormeaux, not just central Montréal.

Where do you incorporate a business in Quebec?

You've got two routes, and a business lawyer will help you choose. You can incorporate provincially under Quebec's Business Corporations Act (Loi sur les sociétés par actions), which the Registraire des entreprises du Québec (REQ) administers. Or you can incorporate federally under the Canada Business Corporations Act, through Corporations Canada, which lets the company carry one name across the country.

The choice affects director residency, name protection, and where you register. Quebec sets no residency requirement for directors, and a federally incorporated company still has to register with the REQ before doing business in the province.

What are your ongoing obligations once you incorporate?

Incorporating is the start, not the finish. Every business registered in Quebec has to file an annual updating declaration with the REQ, even in a year when nothing has changed. Miss two consecutive declarations and the Registraire can strike the registration, which for a Quebec corporation means dissolution. A business lawyer keeps that deadline on the calendar for you.

Quebec is a civil law province, so contracts, obligations, and corporate relationships run on the Civil Code of Québec rather than the common law used across the rest of Canada. Local advice matters here: a shareholder agreement or a supply contract has to fit the Quebec framework. If a deal falls apart, the claim heads to the Cour supérieure or the Cour du Québec, and strict time limits apply.

How do you choose a business law firm in Montréal?

Start with a firm that regularly does your kind of work, from an incorporation to a shareholder dispute to the sale of a business. Ask who will actually run your file, how the firm bills, and whether it can handle both the paperwork and a courtroom if a matter turns contentious. Ask about service in French and English too, since you'll be dealing with Quebec registries either way. Firms sit downtown, in Westmount, and out through the West Island, so there's usually one near your business.

You can confirm any lawyer's standing with the Barreau du Québec. Browse the business & corporate law firms in Montréal below.
