Faulty comparison. 
Both the Vietnamese boat people or Jewish Holocaust survivors were functioning, literate members of well-established societies before war robbed them of their freedom and futures. The wars that threatened both groups were short--just a few years.  They were educated, to some degree, they had skills--and the Vietnamese boat people  were able to FLEE the horror and possible death to somewhere safe and secure.  Jewish survivors did the same after WW II--fled to whatever country would take them, and when they wouldn't, established their own nation.  Where were Canada's Indigenous peoples--those who were left after disease and alcohol did their work--going to flee to?

In B.C., for example, for most of a century, Native peoples were maligned, mistreated, decimated by disease, impoverished, stripped of their culture and religion and, finally, most of a generation rounded up by RCMP and brutalized in schools and hospitals. No comparison is possible.
