Main article: Family Day (Canada)
Nearly 60% of Canadians observe a statutory holiday on the third Monday of February. The holiday is called Family Day in three provinces (Alberta, Saskatchewan, and Ontario), Louis Riel Day in Manitoba, and Islander Day in Prince Edward Island. There is no federally-established Family Day.
Family Day is unrelated to National Family Week, a campaign put on each October by the Canadian Association of Family Resource Programs, a non-profit organization. It is not a statutory holiday, but is generally recognized and celebrated by community organizations across the country.
This holiday was first observed in Alberta in 1990, followed by Saskatchewan in 2007 and Ontario in 2008.
