Importantly, UNDRIP does not automatically grant Canadian immigration status to everyone with Indigenous ancestry
Long before Canada, the United States, and Mexico established their modern borders, Indigenous civilizations flourished throughout the Americas. Today, millions of people in Mexico, Central America, and South America retain Indigenous ancestry, whether through direct community membership or generations of mixed heritage.
Scientific and demographic research illustrates the depth of these ancestral connections. A 2011 mitochondrial DNA study involving Mexican Americans reported that approximately 85% to 90% of maternal lineages were of Native American origin. While mitochondrial DNA traces only maternal ancestry and cannot establish an individual's overall ancestry or Indigenous identity, these findings demonstrate the persistence of Indigenous heritage. Similarly, historical AmericasBarometer survey data found that approximately 78.1% of respondents in Mexico, 92.9% in Bolivia, and 84.4% in Peru identified as Indigenous or mestizo. These figures measure self-identification rather than genetic ancestry, but they highlight the extensive Indigenous heritage found throughout Latin America.
This raises an important question: When Indigenous migrants arrive at North America's borders, including those refused entry into the United States, how should Canada recognize their distinct historical and cultural circumstances?
Canada has endorsed UNDRIP and enacted legislation establishing a framework for implementing its principles. Article 36 recognizes the rights of Indigenous peoples divided by international borders to maintain relationships, cooperation, and connections with members of their communities.
Importantly, UNDRIP does not automatically grant Canadian immigration status to everyone with Indigenous ancestry. Nor does Indigenous ancestry alone establish membership in a particular Indigenous nation. Those distinctions matter, especially because Indigenous peoples have the right to determine their own identity and membership.
