§ Child welfare services fall under the jurisdiction of provincial and territorial authorities, making it difficult to compile statistics at the national level. The most notable variations between provinces include mandate variation by jurisdiction with respect to the age to which children are eligible for services, differences in the length of time a child can receive out-of-home care and the definition of out-of-home care.
