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.

On certain school and transit buses, the Parker single check valve (SCV) that connects with the supply port of the Bendix SR-7 spring brake modulating valve may become excessively worn and eventually break apart. Pieces of the Parker SCV can become lodge inside the SR-7 valve, possibly causing either leakage out of the SR-7 valve or preventing air from properly exhausting from the SR-7 valve. This condition can cause a delay in the application of the parking brakes, the spring brakes not fully releasing or loss of isolation between the primary and secondary circuits. These conditions can occur without warning, leading to unintended vehicle rollaway, brake drag, or in case of loss of primary circuit, inability to modulate the spring brakes. An unattended roll away vehicle could strike a bystander or cause property damage. Correction: Dealers will replace the single check valve (SCV).
The wording above is the department's own, as it stood in the monthly file this site last read. Vehicle counts are the sum of the counts published for each make and model the recall covers. To act on a recall, use the official notice: Transport Canada recall 2007225.

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 Blue Bird Vision Transit Bus, 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 Blue Bird: 242 in the register, and 420 Canadian vehicle recalls filed in 2007.
