Nova Bus LFS in the other registers
This site holds seven national and European registers. Nova Bus LFS is named on 51 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.

Issue:
On certain buses, a programming problem could cause excess diesel exhaust fluid (DEF) to be injected into the exhaust after-treatment system. As a result, there could be a higher than normal amount of ammonia in the exhaust emissions.
Note: This recall only affects buses equipped with a Cummins 2021 model year L9 diesel engine.Safety Risk:
Exposure to elevated levels of ammonia could create a risk of injury.Corrective Actions:
Nova Bus will notify owners by mail and instruct you to take your bus to a Cummins authorized service center to update the software for the engine control module. To reduce the safety risk, Nova Bus and Cummins recommend that you should avoid running the engine in a confined space, such as a service bay, without the use of an exhaust extraction system.

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 Nova Bus LFS, 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 Nova Bus: 131 in the register, and 658 Canadian vehicle recalls filed in 2021.
