What utter hogwash. Look at the slaves taken by the ottomans or the religious  persecution of caucasian minorities all over europe by the catholic church.  The killing of mainly white people and the displaced persons (refugees) during and post ww2 is to this day the largest genocide and refugee situation in history.
None of which denies the suffering or persecution of the first nations or others. But many non white societies (including first nations) were slavers themselves.
It was the white uk that first abolished slavery, and persecuted those engaged in it. Western societies are trying to make amends today whereas many other oppressive countries/cultures are still engaging in ethnic cleansing (rohyinga) and discrimination.

Yet we cannot blame people alive today for the transgressions of the past. We can and should try to make things better for all not engage in silly accusations of race privilege.
If canada is such a bad place to live why do so many immigrants apply to live here?
