This update is part of the Bill C-3 citizenship by descent hub, with the Citizenship guide. CanadaVisa has launched a free online resource named the Family Line Explorer. This tool assists Americans in determining if their family lineage qualifies them for Canadian citizenship by descent. The United States is the largest source country for proof of citizenship applications, with many Americans discovering Canadian ancestors.

Canada's citizenship department faced approximately 136,000 proof of citizenship applications awaiting a decision in September 2026. Under Canadian law, Americans who can trace a direct, unbroken line of descent to a Canadian ancestor are already Canadian citizens. They only need to apply to prove their existing status.

The Family Line Explorer traces a user's family line from a chosen Canadian ancestor. It checks each generation for facts that may break the descent chain. The tool then builds a personalized document checklist. It can also verify if an ancestor used by a relative to prove Canadian citizenship can support a new claim. Users do not need an account or documents to start, and their answers remain in their browser unless a free consultation is requested. Such consultations involve review by the Cohen Immigration Law team.

The launch of this tool follows the implementation of Canada's new citizenship law, Bill C-3. This legislation received royal assent on November 20, 2025, and took effect on December 15, 2025. Bill C-3 removed the first generation limit, a 2009 rule that previously stopped citizenship by descent after one generation born abroad. Immigration, Refugees and Citizenship Canada once provided its own web tool for this purpose, but it was removed when the new law took effect.

Canadian citizenship began in 1947, following Confederation in 1867. Between 1840 and 1930, New England drew hundreds of thousands of French Canadian mill workers. About 30 percent of Vermonters have French Canadian ancestry. A former rule affected those born between February 15, 1977, and April 16, 1981. The new law clarifies that citizenship can pass down through any number of generations. It also states that an ancestor's pre 1947 status as a British subject in Canada is a valid starting point for a claim.

The new citizenship law and the Family Line Explorer tool could help many Americans who hold Canadian citizenship today to prove their status. This may lead to an increase in applications for proof of citizenship and Canadian passports. If users request a free consultation, the Cohen Immigration Law team reviews their family line and results. Immigration, Refugees and Citizenship Canada makes the final decision when it reviews an application for proof of citizenship. Individuals with complex family lines may seek review from a citizenship lawyer at Cohen Immigration Law before they apply.
