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 26V261, 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.

Reading this against the source
This page is what Transport Canada published in the Vehicle Recalls Database, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /canada, and how the reading is done is set out in the method.
What the words on this notice mean — the system it is filed under, and what the filing type says about who found the fault.
This notice names one vehicle among several registers that have written about it. Every notice this site holds for the Heartland Pioneer, in all seven, is kept on that vehicle's own page, with the newest in each.
This register keeps an index of its own for every maker and every year it holds: Canadian recalls on a Mack: 334 in the register, and 405 Canadian vehicle recalls filed in 2026.
