MVSR has a whole section on noise requirements
https://laws-lois.justice.gc.ca/eng/...on-sched6.html

(a) when tested in accordance with

(i) section 3 of Test Method 1106 — Noise Emission Tests (August 2005), the sound level does not exceed 83 dBA when a value of 2 dBA is subtracted from the reported vehicle sound level calculated in accordance with paragraph 3.3.3(c) of that Test Method, in the case of a bus with a GVWR of more than 4 536 kg,

(ii) SAE Standard J1470, Measurement of Noise Emitted by Accelerating Highway Vehicles (June 1998), the sound level does not exceed 83 dBA when a value of 2 dBA is subtracted from the final reported value referred to in section 6.3 of that Standard, in the case of a bus, multi-purpose passenger vehicle, truck or chassis-cab with a GVWR of more than 2 722 kg and not more than 4 536 kg,

(iii) SAE Standard J1470, Measurement of Noise Emitted by Accelerating Highway Vehicles (June 1998), the sound level does not exceed 80 dBA when a value of 2 dBA is subtracted from the final reported value referred to in section 6.3 of that Standard, in the case of a passenger car regardless of its GVWR or any other vehicle with a GVWR of 2 722 kg or less,

Even the BC MVA says it needs to be tested at an inspection station.

Vehicle noise
27 A motor vehicle shall be equipped with an exhaust muffler which complies with section 7.03 of the regulations.

The opinion of an inspector as to whether the engine and exhaust noise is greater than that made by other vehicles in good condition of comparable size, horsepower, piston displacement or compression ratio shall determine whether exhaust gases are expelled with excessive noise.

When tested in an inspection station, the vehicle engine, any auxiliary engine and exhaust level shall not exceed Table 3 standards.
