I gave @kandi a thumbs up. But here comes a personal annecdote anyway.
In 2010 the G20 conference came to Toronto. At the time I was working in an office downtown. For about 2 months the city core was an armed camp. There were several km of k-rail with chain-link fence topped with barbed wire. To get into the conference area you needed to show ID that demonstrated you worked or lived there. There were several hundred additional police borrowed from surrounding regions to bolster the usual Toronto forces. To get to my office I had to walk several hundred meters out of my way to go around the barriers. And there were constantly cops giving me the "stink eye." (I did wear my hair extremely long at the time. A pony-tail to my waist.) During the actual meetings there were huge protests that occasionally became violent. Windows were smashed. Police cars were burned. Many people were roughed up. The police went somewhat berserk with mass arrests resulting, eventually, in a huge settlement payout.
Some time (about 1 year, I don't recall exactly) after that, Her Majesty visited Toronto. I happened to step out of my office heading for lunch just as her motorcade was leaving on the way back to the airport. The entire disruption of my life consisted of less than the time for a traffic light to change once. And I could have avoided that by walking south instead of waiting for the light. But I wanted to stand with the single RCMP officer on the corner. I wanted to see her car and wave to her. Sadly, tinted windows on all the cars meant I could not tell which car was hers.
So a visit from some politicians produced $millions in damages, $millions in lawsuits, and a two month disruption of much of the downtown core. A visit from HM produced no disruption at all, in fact being a pleasant memory.
That's an example of why she was popular with me.
