Bill C‑3 lets millions of Americans claim Canadian citizenship by ancestry

Canada’s amended Citizenship Act, passed as Bill C‑3 in December 2025, removes the previous first‑generation limit and allows anyone with a direct line of descent to a Canadian ancestor to apply for proof of Canadian citizenship. There is no generational cap, and applicants need only demonstrate the lineage.

The change gives eligible Americans access to a Canadian passport and the associated benefits such as unrestricted travel, the right to work or start a business in Canada, and eligibility for provincial health coverage after establishing residence. It also permits the citizenship to be passed to children and subsequent generations born abroad. Analysts note that large numbers of Americans, especially in New England states like Maine where up to one‑third of residents have French‑Canadian ancestry, could qualify.

While the passport alone does not confer a health card, it provides the standing to obtain provincial health coverage once residency requirements are met. The policy is expected to influence retirement planning, cross‑border mobility, and dual‑nationality decisions for a sizable portion of the U.S. population.
