I know that many don't support the Monarchy but for many others Queen Elizabeth II has been a constant in our lives for a very long time.
I first saw her in person in November 1951 in Halifax - I was standing with my mother outside the fence of the Lieutenant Governor's residence waiting to catch a glimpse of the then Princess Elizabeth & her husband as they left to attend a State Dinner. I remember watching the TV broadcast of her 1953 Coronation on a small black & white TV while visiting friends in the USA. Years later I learned that the film was actually from the CBC as they had arranged to develop it aboard the plane flying back to Canada and it was the earliest film available to US TV

The Queen had a remarkable life which did not start off with an expectation of taking the throne, that changed with the abdication of her uncle. A very long and eventful reign.

Now we have King Charles III and lots of changes to look forward to.
