Both registers carry the same date for this defect.
These are the dates each register records against its own notice. They are separate administrative acts in two countries, recorded by two authorities under two sets of rules, and this page does not claim that one caused the other or that owners in either country were contacted on those days. What it shows is that the same manufacturer campaign reached the two registers on different dates.
Read the American notice 26V139, including every earlier version of its wording this site holds. The Canadian register explains why the manufacturer code is published there and what that makes possible. Canada and America sets every matched pair side by side.
