A federal public sector union representing more than 27,000 members is asking the Public Sector Pension Investment Board to divest any holdings in Tesla Inc. from its $264.9 billion portfolio.

In a public statement, the Canadian Association of Professional Employees is calling on PSP Investments and “all pension funds in Canada” to ditch the electric car maker.

“It is deeply concerning that Canadian public sector pension funds are being used to support a corporation whose owner is directly attacking the federal programs and workforce that deliver essential services for millions of ordinary Americans,” said Nathan Prierm, CAPE president and public service pension advisory committee member, in a press release.

Tesla’s chief executive officer Elon Musk has aligned himself with U.S. President Donald Trump as an advisor. Trump drew the ire of Canadians when he slapped the country with import tariffs while repeatedly calling for Canada to join the U.S. as the 51st state.

In an emailed statement to Benefits Canada, a spokesperson at PSP Investments said the organization is proud to be a Canadian pension investor trying to achieve a maximum rate of return without undue risk of loss.

“We are continually monitoring global trade conditions and market developments, evaluating how they may impact our portfolio and adjusting when necessary. Our diversified strategy and long-term focus help us navigate market fluctuations as we continue to fulfill our mandate.”

CAPE said divesting from the electric car manufacturer would send a message indicating Canadian public sector workers and taxpayers won’t support the leader of a company involved with the U.S. administration at a time they’re threatening to annex Canada.

This isn’t the first time Tesla exposure has been the source of difficulties for a pension fund. Earlier this year, Dutch civil worker pension fund Stichting Pensioenfonds ABP sold its entire stake in Tesla, consisting of 2.8 million shares valued at US$585 million. Similarly, the New York City comptroller — an elected official overseeing the management of five public pension systems — said he’s seeking securities litigation against Tesla for significant financial losses and mismanagement.
