Edward Rowe and Patrick Marley co-chair the tax department at Osler Hoskin & Harcourt. They oversee a team of seventy lawyers over five offices in Canada: Montréal, Ottawa, Toronto, Calgary and Vancouver. Tax planners and litigators operate as an integrated unit to provide comprehensive advice. The firm has been recognized as a market leader with tax controversies, but provides a range of services including corporate tax planning, negotiation of mergers, indirect taxation, and more. 

The team at Oslers has remained active throughout the region is transactional tax matters. In Nov 2022, their client Dream Industrial REIT announced a partnership with GIC Private Limited, in connection with a $5.9 billion acquisition of Summit Industrial Income REIT. The firm is currently assisting its client General Motors in an ongoing transaction, in which General Motors seeks to make an $650 million equity investment with Lithium Americas. This large investment into battery production will set General Motors as the largest shareholder of Lithium Americas. 

The Osler’s tax controversy team has also been active during the research period. The firm represents Tax Executives Institute Inc., before the Supreme Court of Canada in an anti-avoidance case. The firm argued the effects associated with the unworkable rule, and successfully got leave for TEI to intervene in the appeal

The firm has been active in recruitment, bringing n three new partners in 2022. Kim Maguire joins the team from Borden Ladner Gervais, Héléna Gagné and Shaira Nanji both join the team from KPMG Canada.

Collaborative professionals, excellent skillset.”

Litigation team is extremely strong.”

Extremely strong Canadian tax practice.

I have had many occasions to work with the tax lawyers at Osler and they are consistently leaders in their areas of expertise.

Osler is one of the leaders in the tax community as it realized before others in the market the "value add" that tax advisors can bring to transactions so had a head start in building out their bench strength and have largely maintained that lead (though the gap in various areas is closing).”
