"Trudeau will recognize Canada's relationship with its Indigenous peoples, challenging any notion that Canada is a "perfect" country"
.
What this says is that Trudeau will address the representatives of 200 countries in a large meeting hall, assuming  that many of them think that his country is the perfect one, and try to convince them that Canada has it's flaws. 'Flaws' is code for human rights violations, discrimination in everything that's good and over representation in everything that is bad, statistical data that is lax to none, a dramatic rise in hate crimes against Muslims and a report prepared by the UN itself slamming Canada for it human rights and racism record a few weeks ago.
The ones who think Canada is perfect are the same ones who are heavily influenced by subliminal advertising in the supermarket and always check the end-of-aisle racks for a bargain. 
Perhaps the ultimate insult to the senses will be if he  takes a bow for welcoming Haitians fleeing the U.S.
