National Family Week originated in Canada and takes place the week before Thanksgiving every year. It was proclaimed an official week by the government of Canada in 1985. National Family Week is celebrated throughout the country with special events put on by community organizations. National Family Week also exists in the United Kingdom, the United States, and Australia.
It is a distinct event from Family Day which is a statutory holiday created by the provincial governments of Ontario, Alberta and Saskatchewan.
National Family Week (French: Semaine Nationale de la Familie) is largely a public awareness campaign, the purpose of which is to celebrate families. Each year FRP Canada, in partnership with other national organizations, creates downloadable resources for families and those who work with families to access when planning an event in their community. With a different theme each year, National Family week highlights various important aspects of family life.
National Family Week offers an opportunity for the federal government to honour families and to introduce new legislation or modify existing laws in ways that it deems will help families.
In 2007, Minister of Human Resources and Social Development, Monte Solberg, stated that "Canada's New Government is proud to celebrate National Family Week and to recognize the important role that families play in this country. Families are the building blocks of our society, and we will continue delivering on our commitment to support and strengthen them.”
