Transport Canada carries this recall as 1979121, dated 12 July 1979. The American register carries the same defect as campaign 15V360, dated 9 June 2015. They are the same defect because the manufacturer filed both under one internal campaign code, SC121.

The two registers are 13,116 days apart: the Canadian entry is dated first, the American one second.
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 15V360, 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.
Mack RS in the other registers
This site holds seven national and European registers. Mack RS is named on 16 American notices. Those are separate campaigns, filed with separate authorities on their own schedules.
The American register
Nothing here says any of these is this notice in another country. A model recalled in one country is often recalled in another, in different words and at a different time, and the authorities do not cross-reference each other. Reading them together is the reason this site holds more than one register.

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 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 209 Canadian vehicle recalls filed in 1979.
