About Andrews Datax.

Andrews Datax is a CPA (Chartered Professional Accountant) firm based in Montreal, Québec providing accounting, business and taxation services. Our office is located on the West-Island of Montreal which will greatly facilitate your traveling experience considering the traffic conditions and our large free parking lot.

Andrews Datax was formed back in 1995 following a partnership including Mr. Doug Andrews and Mr. Richard Kennish who have both since regrettably passed away. These founders had grown the firm over the years due to their focus on small businesses and individuals in the local area.

In 2017, long time dedicated employees decided to continue the journey and purchased the firm. As a sign of respect for the past, they have decided to maintain the company name. So, it’s safe to say we’re a firm with a longstanding and proud history, now driven by a modern team who are keen to see the firm’s future growth.
