About Heather Fisher

Restructuring and insolvency work sits at the centre of Heather Fisher's practice as a Toronto partner with Gowling WLG, with commercial litigation running alongside it. Heather acts for creditors and debtors alike, and for court-appointed officers and others whose interests are on the line when a company restructures or a business dispute heads to court. Corporate restructurings, complex commercial cases and class actions make up the bulk of the work.

Called to the Ontario bar in 2018, Heather has argued at every level of court, from the Superior Court of Justice and its Commercial List to the Court of Appeal and the Supreme Court of Canada. In Ottawa, Heather was one of the Gowling lawyers representing the Canadian Association of Insolvency and Restructuring Professionals as an intervener in two bankruptcy appeals, and presented the association's oral argument when the student loan case Piekut v. Canada was heard in November 2024.

Beyond client work, Heather is active in the wider legal community. After serving as vice chair for 2025 to 2026, Heather now chairs The Advocates' Society's Insolvency Litigation Practice Group for 2026 to 2027, sits on the Commercial List Users Committee, and co-writes case commentary on Supreme Court insolvency decisions for CAIRP's Rebuilding Success magazine. Heather is also on the executive of the firm's national women's network and the board of Action Against Hunger Canada, and Best Lawyers has recognized Heather in Ones to Watch in Canada since 2025.
