The Defenders

Behind a childhood cancer diagnosis, Leucan is there to help the family survive daily life that does not exist anymore.

Defenders are people like you who give back to the community and who are involved in any way in helping families affected by the disease.

Join the gang


The Defenders stop at nothing.

Dare a shaved head, take a ski mountain or the Montreal Old Port by storm, put your strength to the test, form a squad at work: all means work to create a wave of solidarity. Discover the numerous fundraising activities of Leucan.

Challenge yourself


They're heroes every day.

The children need you. Stand together with Leucan’s team, the medical staff and the researchers: change the daily lives of families by giving to Leucan. Your donation is more powerful than you think!



They do good around them.

Use fearless energy to tackle all sorts of important tasks that Leucan activities require.

Be a hero in the lives of children who have cancer and their families.
