McMillan LLP is a Canadian business law firm serving public, private and not-for-profit clients across various industries in North America and around the world.

The firm has industry groups in different sectors such as technology, energy, oil and gas, mining, construction and infrastructure, automotive, and transportation.

Gordon McMillan joined the firm in 1921 and practiced for over half of a century, bringing notable clients such as Monarch and BorgWarner.

Throughout the 1940s and 1950s, Binch would drive from Toronto throughout the mid-west and Chicago to solicit work from mid-sized U.S. companies looking to expand into Canada.

His pioneering work opened a north–south corridor between McMillan Binch and American businesses that, at the time, belied the trend in many Canadian firms to patch together national networks running east–west.

The Right Honourable Jean Chrétien practiced with Lang Michener from 1986 to 1990, and Michel Bastarache was appointed a Justice of the Supreme Court of Canada in 1997.

As a sister firm embedded in McMillan LLP’s offices, Vantage services a wide range of Canadian and international clients: 2022 McMillan LLP was included on the Advisory Centre on World Trade Organization Law (ACWL) roster of external legal counsel.
