Photos and good wishes offered to longest-reigning British monarch as official celebrations get underway

Queen Elizabeth turned 90 on April 21 — another significant milestone for the woman who became the longest-reigning British monarch last year. This weekend, official celebrations marking her birthday will take place throughout London.

The Queen has made 22 officials visits to Canada, most recently in 2010. Each time she travelled across the country, Canadians came out to greet her, often snapping photos to remember the royal visit.
