Immigrants!...Indigenous?

How many different languages you now hear when you are in a major urban center? The last time I was in downtown Calgary, I heard Spanish, Hungarian, Russian, Romanian, French, Arabic, Congolese, Estonian, Norwegian, Icelandic, Japanese, Chinese, South Korean, Figian, Hawaiian, German, etc. I guess these immigrants were not enforced not to speak their language when entering Canada: unlike us, the Aboriginal people through the government funded residential school system, were not allowed to speak our own language. Where is the justice?
