OTTAWA - An immigration lawyer is pushing back on Immigration Minister Lena Diab’s claim that genealogical records — including those from third-party ancestry sites — are not sufficient evidence for a citizenship-by-descent claim.

While an unknown number of citizenship-by-descent claimants have recently received letters from Diab’s department telling them to surrender their citizenship certificates, government practices and the department’s own document checklist do not state that records from sites like Ancestry.ca cannot be used as evidence for a claim.
