"Frequently referred to as "Canada's birthday", particularly in the popular press, the occasion marks the joining of the British North American colonies of Nova Scotia, New Brunswick, and the Province of Canada into a federation of four provinces (the Province of Canada being divided, in the process, into Ontario and Quebec) on July 1, 1867. Canada became a kingdom in its own right on that date, but the British parliament and Cabinet kept limited rights of political control over the new country that were shed by stages over the years until the last vestiges were surrendered in 1982, when the Constitution Act patriated the Canadian constitution."

Under the federal Holidays Act, Canada Day is observed on July 1, unless that date falls on a Sunday, in which case July 2 is the statutory holiday, although celebratory events generally take place on July 1, even though it is not the legal holiday. If it falls on a Saturday, any businesses normally closed that day will generally dedicate the following Monday as a day off.

In the Detroit, Michigan and Windsor Canada areas they have a celebration called the Freedom Festival (that celebrates both the July 1 & July 4) which culminates with a Fireworks display on a barge in the middle of the Dertroit River. The cost of this display was born by Target & now I think the billionaire owner (Mike Ilitch)of Little Ceasars, Detroit Tiger & Red Wings) does now.

Was born, raised and educated on the south side of Detroit and visit family in the area now & then and enjoy Labatt's Blue when I take the bridge over & tunnel back - have to travel south to get to Canada.
