Generations of Mexican families may already be Canadian, and eligible for Canadian passports

The Canadian Citizenship Act was amended on December 15 2025 (Bill C‑3). The amendment eliminated the “first‑generation limit,” allowing people born abroad before that date to inherit Canadian citizenship from any ancestor who was a Canadian citizen, no matter how many generations separate them. Applicants must still prove the lineage to a qualifying ancestor.

Historical migration that created the Mexican‑Canadian pool

• Mennonite settlement (1922‑1930) – About 6,000 Mennonites left western Manitoba and Saskatchewan after the provinces tightened control of German‑language schools. Between 1922 and 1930 they travelled by chartered train to Chihuahua (Ciudad Cuauhtémoc) and Durango (Nuevo Ideal). By 1965 an estimated 35,000 Mennonites of Canadian origin lived in Mexico.
• Other Canadian migrants – Early‑20th‑century Canadian engineers, investors, and retirees settled in Mexico City, Lake Chapala, Puerto Vallarta, Los Cabos and Monterrey. Thousands of Mexican‑Canadian couples have also had children in Canada who later returned to Mexico.

Because Canadian citizenship did not exist before January 1 1947 (people were British subjects), the new law treats anyone born in Canada before 1947, or naturalised there before that date, as a Canadian citizen for descent purposes, even if they later lost British‑subject status.

How to determine if you have a Canadian ancestor

• Surnames common in Mennonite colonies – Sawatzky, Fehr, Friesen, Penner, Wiebe, Klassen, Dyck, Neufeld, Reimer.
• Birthplace clues – Ancestors born in Manitoba, Saskatchewan, or the specific districts of Swift Current, Hague‑Osler, or the Zuloaga estate in Chihuahua before 1926.
• Geographic ties – Roots in the Cuauhtémoc region (Chihuahua) or Nuevo Ideal (Durango).
• Community names – Villages still called “Manitoba” or “Swift Current” in Mexico.
• Language and migration stories – Low‑German spoken, family narratives of arriving by train in the 1920s.
• Naturalisation records – Ancestors who became British subjects in Canada before 1947.
• Modern Canadian enclaves – Parents who are Canadian residents in retirement towns such as Chapala, Ajijic, Puerto Vallarta, Mazatlán or Los Cabos.

Research resources

Only original certificates (birth, naturalisation, civil acta) are accepted as evidence; index entries alone are insufficient.

Applying for citizenship by descent

1. Gather primary documents – Canadian birth certificate of the qualifying ancestor, or pre‑1947 naturalisation certificate.
2. Assemble the chain – Birth (or marriage/death) certificates linking each generation from the Canadian ancestor to the applicant.
3. Submit a Proof of Citizenship application to Immigration, Refugees and Citizenship Canada (IRCC).
4. Assessment – Officers apply a “balance of probabilities” standard; missing documents do not automatically disqualify a claim if the overall evidence is convincing.

If approved, IRCC issues a citizenship certificate, which can be used to apply for a Canadian passport.

Benefits of Canadian citizenship for Mexican residents

• Dual nationality – Mexico permits dual citizenship; Mexican citizenship is retained.
• Mobility – Visa‑free entry to Canada, ability to live and work anywhere in Canada without a permit.
• Travel to the United States – Canadian citizens do not need a U.S. visa, unlike Mexican passport holders.
• Taxation – Canada taxes residents, not citizens; a dual citizen residing in Mexico owes Canadian tax only on Canadian‑source income or assets.
• Health care – Provincial health coverage is available after establishing residence in a province.
• Transmission to descendants – Children of a Canadian citizen automatically inherit the right to claim citizenship.

The amendment opens a pathway for tens of thousands of Mexican families—particularly descendants of the early 20th‑century Mennonite migration—to obtain Canadian citizenship and its associated rights.
