Matteslaw Legal Professional Corporation is a solo practice led by Joe Mattes, a barrister, solicitor and notary public in Waterloo, Ontario. The office sits at 24 Dupont Street East, in Uptown Waterloo, and the work centres on corporate and commercial law. That runs from incorporations and reorganizations through business acquisitions and divestitures, commercial leasing, and secured transactions, and it extends into wills, estate administration, and business succession planning. A recurring thread is technology and trademark work, which the firm's own materials have emphasized for years.
Joe Mattes earned a Bachelor of Arts from the University of Toronto in 1980 and a law degree from Western University in 1983, then was called to the Ontario bar in 1985. Before opening an independent practice, the founder practised in Toronto and was a partner at a large Waterloo firm. Since 1996 the practice has published a newsletter, Technology Businesses and the Law, along with articles on business and estate topics. Matteslaw serves mostly business and professional clients, and it's accepting new work by referral only.
Wheelchair accessible
By appointmentThe office is at 24 Dupont Street East, a short street just off King Street North that the firm calls the heart of Uptown Waterloo. Uptown is the city's older commercial core, a walkable run of storefronts, restaurants, and professional offices in the Business Improvement Area rather than a highway plaza. It's also a stone's throw from the technology and startup economy that Waterloo is known for, which lines up with a practice that has long handled incorporations, reorganizations, and technology and trademark matters. For an owner coming in to sign a lease, close a sale, or set up a succession plan, it's a central and easy place to reach.
