Stewart McKelvey is a full-service Canadian law firm and one of the largest in Atlantic Canada. The firm advises employers, plan sponsors, and both public and private sector organizations on a range of legal matters. Its pensions and benefits group works with some of the region’s largest pension plans across multiple industries.
The firm’s story predates its 1990 founding by nearly a century. Stewart MacKeen & Covert, the oldest of the four founding firms, traced its Halifax roots back to 1892.
By the late 1980s, free trade with the US pushed Atlantic Canadian clients into a bigger and more complex marketplace. That shift became the case for building a firm with a broader regional reach.
On May 1, 1990, four leading Atlantic Canadian firms merged to form Stewart McKelvey Stirling Scales. J. William “Bill” Mingo, managing partner of Stewart MacKeen & Covert, drove the deal as a direct response to free trade and client globalization.
The new firm launched with more than 125 lawyers and became the largest in Atlantic Canada from day one. The other three founding firms were:
By its tenth anniversary in 2000, the firm had grown to 175 lawyers across multiple offices. In 2006, it dropped “Stirling Scales” from its name and has gone by Stewart McKelvey since.
As the firm grew, Lexpert listed it among Canada’s largest law firms, with more than 250 lawyers across six offices today.
The firm’s evolution also showed up in its leadership. In 2015, Lydia Bugden, K.C. became CEO and Managing Partner, a role the firm says no woman had held at an Atlantic Canadian law firm before. In 2023, its Partnership Board reached gender parity, with 50 percent of seats held by women.
Stewart McKelvey offers legal services across multiple practice areas from its six Atlantic Canadian offices.
