About Carl Hinzmann

Carl Hinzmann runs a transactional and advisory tax practice for businesses, investors and families. As a partner in Gowling WLG's Toronto office, Carl combines Canadian income tax with corporate law, on transactions and as an ongoing advisor. Clients range from public and private companies, fund managers and financial institutions to tax-exempts, institutional investors, high-net-worth families and investors based outside Canada. Carl's aim is practical, usable advice that weighs commercial realities against the legal and tax rules.

A good share of the work involves money coming into Canada from abroad, Canadian real estate in particular. German is part of the toolkit too: Carl was born in Germany, came to Canada at age seven and is still fluent, with Level I and II of the Deutsches Sprachdiplom, the German Speech Diploma.

Carl's background is in finance as well as law. At Gowling WLG, Carl was on the team that advised the Workplace Safety and Insurance Board on its 2020 conversion of its single employer pension plan into a jointly sponsored plan, working on tax and investments. Carl also had a seat on the team for Real Tech, a Whitby water monitoring company, when ABB agreed in January 2024 to acquire it.

In April 2024 Investment Executive spoke with Carl twice: once about Ottawa's consultation on simplifying the qualified investments rules for registered plans, which Carl called useful and probably much needed, and once about how mutual fund corporations and trusts pass capital gains through to their investors as the inclusion rate was set to rise. Carl has contributed to Gowling WLG's analysis of the 2023, 2024 and 2025 federal budgets as well.

Practice areas

Tax Law Business & Corporate Law

Tax and corporate structuring for deals and funds

Carl handles the income tax and corporate law sides of mergers and acquisitions, fund and investment structures, and reorganizations of corporations and corporate groups. Joint investments that bring tax-exempts, non-residents and taxable Canadians together are a regular part of this work.

Large reorganizations and agreements

Some of Carl's reorganizations involve dozens of entities, and sometimes hundreds. Carl has led structuring mandates that together reach every continent except Antarctica, working with foreign counsel in many jurisdictions, and prepares the detailed agreements that hold these structures together, from shareholder and partnership agreements to joint ventures.

Non-resident investment in Canada

For non-residents holding Canadian real estate, Carl advises on section 116 compliance and section 216 elections. Carl also helps non-residents who want to expand into Canada, whether they build a business here or buy one.
