I have vacationed in Canada many many times. From British Columbia to Nova Scotia, the only place I haven't visited that is still on my list is Alberta. I have wonderful memories of so many trips.
My mother's oldest sister lived in Windsor. We were about twenty minutes from the Detroit-Windsor tunnel and made many trips across the border. Other cousins lived in Leamington and Toronto. Here is a video about the tunnel.
Detroit and Windsor have long celebrated their holidays of July 1 and July 4 together. Many years ago their was an International Freedom Festival. Since I was in downtown Detroit from 1964 until 1977, I often participated as evidenced by this 1973 photo.
Five years ago I made my second trip to Victoria, BC for my son's wedding. We enjoyed the holiday celebrations on the following day, today. Whistler, Victoria and Vancouver, BC; Thunder Bay, Agawa Canyon, Toronto, Niagara Falls, rafting on the Niagara River rapids, Manitoulin Island, Point Pelee, Windsor, Hamilton, London etc., Ontario; Montreal and Quebec City, Quebec; driving along the St. Lawrence River to the northern tip of Maine; Nova Scotia and Cape Breton; Prince Edward Island.... Canada is an incredible place to visit.
If you would enjoy learning more about this country, I highly recommend watching Canada: The Story of Us. I found it very enlightening and entertaining.
And to those of you Canadians celebrating your birthday, have fun. Just take it easy on those fireworks.
