According to Canadian law, same-sex marriage is:

Discover Canada records this in one direct sentence. The guide writes: Canada's diversity includes gay and lesbian Canadians, who enjoy the full protection of and equal treatment under the law, including access to civil marriage. The legal status the test wants is therefore allowed (legal access to civil marriage).

Two distinct guarantees in one sentence. Discover Canada commits gay and lesbian Canadians to TWO specific guarantees: full protection and equal treatment under the law AND access to civil marriage. So same-sex marriage is allowed AND legally protected — meaning gay and lesbian Canadians can marry each other on the same legal terms as opposite-sex couples.

The wording is precise. Discover Canada uses three specific words: "full protection," "equal treatment," and "access." So the protection is not partial, the treatment is not different, and the marriage right is genuine access. The phrasing is the strongest legal-rights phrasing applied in the source — making the protection comprehensive rather than limited.

The statement sits within Canada's diversity framework. Discover Canada writes that "Canada's diversity includes gay and lesbian Canadians" — placing them as one of the named groups within the country's diversity. The guide also writes that "together, these diverse groups, sharing a common Canadian identity, make up today's multicultural society." So gay and lesbian Canadians are part of the broader multicultural society the guide describes, alongside Muslim, Jewish, Hindu, Sikh, and other religious and cultural groups. The protection-and-civil-marriage commitment is part of Canada's overall framework of treating all members of its diverse society as equal under the law. So when the test asks the legal status of same-sex marriage in Canada, the source-precise answer is: allowed, with full protection of and equal treatment under the law, including civil-marriage access.

The question is testing whether new citizens know the legal status of same-sex marriage. Discover Canada commits to one position: allowed (with civil-marriage access). The right test answer matches that.

The wrong answer choices each substitute a different status. "Not allowed" reverses the source — same-sex marriage is allowed across Canada. "Allowed only in some provinces" is wrong — Canadian federal marriage law gives gay and lesbian Canadians equal access nationally. "Under review" is wrong — the protection is settled in Canadian law. Only the allowed answer matches the source.
