RSM Canada opens new flagship Toronto office, marking a major growth milestone

New location underscores the firm’s strong growth since 2017 and ongoing commitment to client service excellence.

TORONTO, ON – (Sept. 21, 2026) – RSM Canada, a leading global provider of consulting, tax and assurance services, today announced the opening of its new Toronto office at 66 Wellington St. W. in the TD Bank Tower, a flagship location that reflects the firm’s rapid growth and long-term strategic investment in the Canadian market.

Since 2017, RSM Canada has grown by more than 289 per cent and now employs over 900 professionals across six locations. The new office marks an important milestone and signals the firm’s commitment to Toronto, a leading global business centre and a key engine of Canada's economy.

The investment strengthens RSM Canada's ability to serve clients by bringing multidisciplinary teams together, deepening client engagement and providing businesses with access to specialized expertise from across Canada and the world.

Home to nearly 550 professionals in the heart of Canada’s financial district, the office will serve as a hub for connection, innovation and client service. Designed to bring diverse capabilities together, the space will help clients draw on broader perspectives to solve complex business challenges and capitalize on growth opportunities.

"Opening our new Toronto office represents far more than a change of address," said Harry Blum, national managing partner with RSM Canada. "Since launching RSM Canada in 2017, we've grown from a single office in Toronto into a firm of over 900 professionals serving clients in six offices across the country. This new office reflects that growth, the momentum we continue to build across Canada and our confidence in the opportunities ahead for our people, our clients and Canadian businesses."

"Toronto is where RSM Canada's story began, and this office represents the next stage in that journey," added Rhonda Klosler, chief operating officer and Ontario market leader with RSM Canada. "Toronto plays an important role in how we support clients, attract top talent and bring our people together. Our new space builds on that foundation—creating more opportunities for our teams to collaborate, work alongside clients and connect businesses with the specialized expertise of RSM professionals across Canada and around the world."

Through its integrated North American platform, RSM Canada combines deep local market knowledge with the scale, resources and capabilities of one of North America's leading professional services organizations. Clients benefit from seamless service across borders and access to specialized industry, consulting, tax and assurance expertise wherever they do business.

While RSM Canada was officially established in 2017, its Toronto roots run much deeper - the Toronto practice has served businesses in the market since 1962 and formed the foundation for what would become RSM Canada.

The new office positions RSM Canada for its next phase of expansion, creating opportunities to deepen client relationships, attract top talent and strengthen connections across the firm's Canadian and global networks.
