I’m Canadian in Ontario and the first five years of my life, all I spoke or heard was my cultural language Ojibway-Cree. I went to school where I learned English but continued to only mostly speak my language.
Then I spent an awkward period as a teenager speaking English with a Native accent … a classic TV stereotypical Native accent and it was horrible. It took me about a decade to get over that phase, now I speak English as boringly as any Canadian. Not bad eh?
