Madam Speaker, that is a very good question.
When it comes to the rules for people immigrating to Canada, there is a requirement that they be able to speak one of our two official languages, for example. This is mandatory for people seeking citizenship who were born in a foreign country and who do not have a parent or grandparent who was born in Canada. I think this is a reasonable requirement for people who are in the same situation but who do have a parent or grandparent who was born in Canada.
The rules are there to ensure that both official languages are spoken by the majority of Canadians across the country.
