About grit + co

Grit + co is a Toronto corporate and commercial law firm founded by Josh Calderon, who was called to the Ontario Bar in 2012. Calderon began at one of Canada's largest business law firms, then left in 2016 to launch a travel technology startup. After about a year and a half, that venture ended, and Calderon combined a legal background with an interest in entrepreneurship to start grit + co.

The firm advises small and medium sized business owners on mergers and acquisitions, corporate and tax driven reorganizations, equity financings, and commercial agreements such as customer and vendor contracts. Its M&A work spans sectors including software, e-commerce and retail, franchises, creative agencies, financial advisory businesses, and construction trades such as electrical, HVAC, and plumbing. Grit + co also helps structure business relationships through incorporations, shareholder agreements, and family trusts, and works with businesses that are financially viable but going through a difficult stretch.

Instead of billing by the hour, the firm prices its ongoing work through fixed monthly packages and quotes one off transactional projects as a fixed price for a fixed scope.
