"...That’s Victoria Day in most of Canada..."

I don’t understand Canadians admiration backward without limit for the monarchy 
and “Why” are they so PROUD (?) of that family ?
I don’t understand “Why” Canadians are so PROUD 
of “Queen Victoria” and her “Victoria Day” in Canada ???
The BIGGEST Opium dealer of all time!
(Blast!)
Never heard, Anglo Canada, about “Opium Wars” ?

Lady Victoria became Queen at 18, in 1837.
At 20 when Britain, in 1839, said once the war to China for the "monopoly" of opium and she won!...
and China will pay it dearly ! The Brits 'confiscates' Hong Kong for...99 years, remember ?  
(Their serving as base for the production and export of opium trafficking.)
And Paf! In 1856, yet another declaration of war of Victorian Britain to China!  
Unmet deemed "insufficient" concessions 
this time above Britain's Queen Victoria gets the...“Total Legalization of the Opium trade”.
Yes Sir ! Nothing less !
“Cheers to Queen Victoria”, so they say ???
