The long weekend holiday to celebrate the origins of the Canadian state, its history, society, and culture starts on Friday (on Thursday nite for some) and continues until work starts again on Monday. But the day itself in which Canada's birthday is celebrated is June 1. God bless Canada. - Politicarp

Here's a snippet from Jasper Booster netlink for the Jasper, Alberta, tourism town at the edge of one of Canada's great national parks:

Celebrate Canada Day
July 1 is a special day to celebrate the creation of the dominion of Canada back in 1867. It was on this date that three British territories -- the Province of Canada (southern Ontario & southern Quebec), Nova Scotia and New Brunswick -- were united into a federation known as Canada. The July 1 holiday was established by statute in 1879, under the name Dominion Day; it was not until Oct. 27, 1982, that the official name of the holiday was changed to Canada Day. To help commemorate this special occasion join in the festivities that include a pancake breakfast, flag raising ceremony, Centennial Park activities, a parade and fireworks.

People will be flocking to the campsites of the national parks all across the coutry. In Ontario, there will be a vast pollutodash by autos, swarming off from the metropolis to what's called Cottage Country, where many in Toronto's middleclass, for instance, retreat as much as possible for the summer.
