What does a business lawyer do?

Business and corporate lawyers help companies form, grow, and transact: incorporating, drafting shareholder and partnership agreements, negotiating contracts, and handling financings, sales, and acquisitions.

A company can incorporate federally or in a single province, and the choice affects filings and name protection, so it's worth knowing which fits before you file.

How do you choose the right firm in Windsor?

Match the firm to your stage. Ask about its experience with businesses your size and in your sector, and how it bills for ongoing work versus one-off deals.
