About Barrett Tax Law

Clients rate this firm highly on Google.

Barrett Tax Law is a Canadian tax and corporate law firm founded by Dale Barrett in January 2009. Its head office is in Concord, Ontario, and the firm describes its practice as concentrated on tax and corporate matters rather than general legal work. It says it has represented more than 15,000 clients across Canada since it opened.

The firm's tax work covers CRA audits, notices of objection, voluntary disclosures, and appeals to the Tax Court of Canada, along with GST/HST disputes under the Excise Tax Act. On the corporate side it handles incorporations, reorganizations, shareholder agreements, and succession planning for business owners, and it advises on cross-border tax questions between Canada and the United States.

Barrett was educated at McGill University's law school in both civil and common law, articled at Torys LLP, and was called to the bar in 2009, the same year the firm was founded. Barrett is a licensed member of the Law Society of Ontario, the Law Society of British Columbia, and the Law Society of Alberta, has written several books on Canadian tax including Tax Survival for Canadians: Stand Up to the CRA, and writes a tax column for The Lawyer's Daily. The firm won the Consumer Choice Award in 2021.

The neighbourhood

The Concord head office is the firm's base in Ontario. Because the firm's core work, CRA disputes and Tax Court of Canada appeals, is conducted largely by correspondence, phone, and hearings held across the country rather than at a single local courthouse, the Concord address functions as an operations base for a national practice more than a walk-in storefront tied to one court.

The firm's practice-areas page also lists offices in several other cities, including Vancouver, Calgary, Edmonton, Fort McMurray, Ottawa, Toronto, and Winnipeg, giving it a presence across the country for clients dealing with the same kind of CRA and Tax Court matters.
