OTTAWA: Canadian immigration officials are using DNA testing and ancestry websites to try to establish the nationality of migrants, the Canada Border Services Agency said on Friday.

CBSA spokesman Jayden Robertson said the agency uses DNA testing to determine identity of “longer-term detainees” when other techniques have been exhausted.

“DNA testing assists the CBSA in determining identity by providing indicators of nationality thereby enabling us to focus further lines of investigation on particular countries,” Robertson said in an email.

But the process raises concerns about privacy of data held by ancestry websites, and highlights political pressure over the handling of migrants by Canada’s Liberal government. More than 30,000 would-be refugees have crossed the US-Canada border since January 2017, many saying they were fleeing US President Donald Trump’s immigration policies.
