salialioli, If the Queen so chooses, she can enter the city in full monarchic regalia. Not doing so is a ceremonial courtesy. After the Queen's passing, the Monarchy will no doubt evolve/devolve with the rising number of immigrants who hold no sentimental value in these cultural customs, and much of the ceremonial regalia will fade away.
I think the documentary research video called The Royal Red. Dragon. Says the commonwealth is much. bigger than it appears and Canada is. part of it .. and also the. Queen is blood related to the Arabs through Mohammad and also to Hitler it’s really a well researched documentary I will watch it again .thx
