First, the Government of Canada's policy is to offer Canadians services in the official language of their choice, regardless of their language skills. A bilingual person shouldn't be treated any differently from a unilingual person. Everyone who visits a federal office has the right to choose the official language in which they wish to receive service, according to their needs.
We wondered what led to this increase in the number of people who may want to receive service in the minority language. This is the impact of this new calculation method. The goal is to count all the people across Canada who use a minority official language at home. We then consider that all these people, such as francophones outside Quebec, might want to receive service in French.
The fact that the post office now provides services in both official languages doesn't make it any less anglophone or francophone. This certainly wasn't the intention of the Governor in Council upon establishing these regulations.
