Princess Margaret has launched a $2.5-billion fundraising campaign aimed at changing how cancer is detected, treated and experienced by patients across Canada and around the world.
The Princess Margaret Cancer Foundation announced the Carry The Fire campaign on September 22, 2026, describing it as the largest cancer fundraising campaign in Canadian history.
The campaign launch was accompanied by an anonymous $100-million donation from a donor with a personal connection to cancer.
The foundation said the gift is the largest ever received by the organization and the biggest donation directed toward cancer in Canadian history.

Three priorities for the Princess Margaret campaign
The Princess Margaret campaign will direct philanthropic investment toward three main areas: detecting cancer at its earliest stages, developing alternatives and additions to traditional chemotherapy, and expanding support for patients and their families.
Stage 0 and earlier detection
The first priority, called Stage 0, focuses on preventing cancer, intercepting disease before it progresses and finding cancer earlier, when treatment may be more effective and less invasive.
The strategy includes research into screening, genomics, liquid biopsies and other tools that could identify molecular signs of cancer before conventional testing detects a visible tumour.
Princess Margaret researchers are already studying molecular residual disease, which refers to small traces of cancer that may remain in the body after treatment and later contribute to recurrence.
Beyond chemotherapy
The second priority is aimed at advancing precision medicine, immunotherapy, cellular therapies, theranostics, genomics and artificial-intelligence-supported care.
Theranostics combines diagnostic imaging with targeted treatment, allowing clinicians to identify cancer cells and deliver therapy more directly to affected areas.
The foundation says the goal is to develop treatments that are more personalized and effective while reducing unnecessary side effects.
Boundless Cancer Care
The third priority, Boundless Cancer Care, focuses on the broader experience of living with cancer.
That work includes survivorship services, rehabilitation, mental-health resources, caregiver support and other forms of care that extend beyond medical treatment.
The foundation said the approach recognizes that cancer affects patients, families and caregivers before, during and after treatment.
Anonymous donor gives $100 million
The donor behind the $100-million gift has not been identified publicly.
The foundation said the donor did not restrict the donation to a single disease or program, giving Princess Margaret flexibility to direct the money toward its highest-priority needs across research, education and patient care.
That flexibility could allow the cancer centre to respond more quickly to promising research opportunities, emerging technologies and changing patient needs.
The donation also provides an early signal of the scale of philanthropic support the campaign is seeking as it moves into its public phase.
Why Princess Margaret is expanding its research push
Princess Margaret Cancer Centre is part of Toronto’s University Health Network and provides specialized cancer care for both inpatients and outpatients.
UHN says the centre has more than 3,000 staff, 12 site groups, 26 specialty clinics and more than 400,000 patient visits each year.
The centre treats more than 200 types of cancer and operates one of the largest radiation-treatment programs in the country.
Its research agenda includes early detection, clinical trials, radiation medicine, personalized treatment and technologies designed to move discoveries from laboratories into patient care.
The campaign comes as cancer researchers face both rising demand for care and rapid advances in fields such as artificial intelligence, genomics and cellular therapy.
For patients, the central question will be how quickly fundraising commitments translate into accessible tests, clinical trials, treatments and support services at hospitals such as SickKids Hospital.
What happens next
The Princess Margaret Cancer Foundation will continue building the campaign through donors, volunteers, research partners and community fundraising events.
The foundation has not announced a deadline for reaching the $2.5-billion target.
It also has not provided a public breakdown showing how much of the overall goal has already been secured beyond the newly announced $100-million gift.
The campaign’s three priorities are expected to guide future donations and major investments at Princess Margaret Cancer Centre.
For patients and families, the immediate impact will depend on how individual programs are selected, funded and implemented in the years ahead.
