The Canadian Cancer Research Alliance (CCRA) is a collaborative of 31 Canadian cancer research funding organizations including government funding programs and agencies, cancer care agencies, cancer charities, and other voluntary associations, that collectively fund most of the cancer research conducted in Canada.  It is our belief that through effective collaboration, Canadian cancer research funding organizations can maximize their collective impact on cancer control and accelerate discovery for the ultimate benefit of Canadians affected by cancer.  The CCRA supports the AllTrials campaign to have all clinical trials registered and all results reported.  This effort to increase transparency will promote knowledge sharing for the ultimate benefit of all.
