@R181 Bob, you make an interesting point because of my personal experience. I didn’t settle in Canada utntil I was 19 years old, 56 years ago. Over time I’ve lost most of my non-Canadian accent to such an extent that only a few people can identify that I’m not born and bred in Canada. I have several friends who have also settled in Canada for nearly as long as I have, and they haven’t picked up a CanadIan accent to any great extent. My wife is one of them. She came to Canada about five years after I did and to this day she has retained her Hampshire accent; interestingly, when we are in England, which is a yearly occurrence, her English accent is much more pronounced, as it is when she speaks with her friends and family in England on the phone
Your story has some common points with mine, except for the different respective ages when settling in a foreign country.
Born in Romania, moved to Spain when I was 11, my brother was 15. To this day, if I don't say I am Romanian, no one can tell.
We were having a coffee once in Madrid, with my wife and my in-laws, all of them born and bread in Bilbao, on the Northern coast, the city my family and I settled in when we emigrated. It is an area with a very strong accent and a particular way of speaking Spanish.
The waiter in Madrid came to take our order, straight away asked us if we were from Bilbao. When given an affirmative answer he replied "I was sure of it, he (pointing towards me) has SUCH A STRONG Bilbao accent!"
Yet my brother never managed to pick the local accent as well as I did
