The Leukemia & Lymphoma Society of Canada

The Leukemia & Lymphoma Society of Canada (LLSC) is a national non-profit organization dedicated to curing blood cancers and improving the quality of life for patients and their families. Through Canadian-led research, education, advocacy, and free support services, LLSC helps people navigate every step of their blood cancer experience while driving progress in treatments and care.

Light The Night is LLSC’s signature fundraising event, bringing communities together each fall in cities across Canada. Participants carry illuminated lanterns—red for supporters, white for survivors, and gold in memory of loved ones—as they walk in solidarity to honour, celebrate, and remember those impacted by blood cancers.

Funds raised through Light The Night fuel groundbreaking research and vital support programs. The event not only shines a light on the progress made over the past two decades, but also inspires hope and connection, reminding everyone that no one walks alone in the blood cancer community.
