The grand duchess olga alexandrova sister of czar nicholas ii spent the last 12 years of her life living in or near which Canadian city?

I believe Toronto. do not confuse with Olga Nicolaievna- Grand Duchess of Princely Rank ( the oldest) l895-l9l8 who died in the Massacre. Olga who was the sister of the Czar, lived until I believe l96l. By the Way Grand Duchess Olga ( the name roughly translates as ( Grace)) was six foot two and had eyes of blue, I said that "Cat was an Amazon!- this is Nicholas" Daughter not his sister!
