On Thursday, Oct. 22, 2026, the Larry and Judy Tanenbaum Family Foundation made a C$25 million donation to the Terry Fox Foundation, the largest single donation in the Terry Fox Foundation's history. The release is datelined Toronto and the matching funds come from the Government of Canada, so this article reads the bare dollar figures in the release and in CP24 as Canadian dollars, marked C$. The announcement came as the Terry Fox Foundation and the Terry Fox Research Institute unveiled "Powered by Terry," the second chapter of their Finish It campaign, which asks Canadians to help take Terry's Marathon of Hope across the finish line.
What the C$25 Million Tanenbaum Donation Unlocks for Cancer Research
The release said the Tanenbaums' commitment unlocked matching funds from the Government of Canada, creating C$50 million in impact for cancer research. The release did not state the size of the federal match, but the Toronto Sun reported that the federal government will match the donation. The gift equals about 30.3 percent of the two charities' combined fiscal 2025 revenue, according to Charity Intelligence figures.
The donors said they were proud to support the Marathon of Hope Cancer Centres Network, which the Terry Fox Research Institute leads and which unites 57 member institutions across Canada.
Michael Mazza, chief executive officer of the Terry Fox Foundation, said, "This is a landmark moment for the Terry Fox Foundation," and that the commitment matters for what it makes possible, not only for its size.
Larry Tanenbaum, former chairman of Maple Leaf Sports and Entertainment (MLSE), said the funding will support a national network of researchers across the country. In his words, "Sixty-some-odd institutions across Canada, 1,300 researchers across Canada, all working for the same thing: sharing information on an open science basis," which describes the network.
Larry and Judy Tanenbaum said in the release: "We believe deeply in Open Science whereby collaboration and sharing knowledge is for the greater good in accelerating discovery."

By size, the donation sits in the lower half of that ledger. It is about 30.3 percent of one year's combined revenue for the two charities, as the next section shows.
How Much of the Two Charities' Combined Revenue the Donation Represents
Charity Intelligence reports consolidated total revenues of 82.554 million dollars for fiscal 2025 for the Terry Fox Foundation and the Terry Fox Research Institute, with transfers between the two charities excluded. Charity Intelligence prints its figures in thousands with no currency code. This article reads them as Canadian dollars, as it does the gift. The C$25 million donation equals about 30.3 percent of that total. The profile's fiscal years end in March and were last updated on Sept. 5, 2025.
The C$50 million total depends on a federal match that the release did not size, so the release alone could not show how much of that total is new money.
