I have experienced both situations. As an anglophone, I was transferred to Bagotville. I was a minority in a culture that was very welcoming and patient.
That said, I think there is a duality of existence. However, many of the services for those who are serving and who do move around the country are very deliberate in their efforts to reach minorities as a priority, regardless of whether that is inside Quebec, where there is arguably a large majority of francophones, or outside of Quebec, where you might be in Moose Jaw, Saskatchewan, but you can be served by the family resource centre in the language of your choice. They will help you find access to child care services that are in the language of your children. There are tremendous efforts, institutionally and with their partners, to try to make sure that minorities feel at home, regardless of where they live.
That is a general statement. There are gaps. There are cases I personally dealt with when I was in uniform where it didn't work and we had to intervene to try to restore the sense of feeling community and feeling connected, especially for those of a different language.
