Here is a test, deflate a tire and go for a drive. The car will tell you there is a tire pressure problem but it cannot tell you which tire. In a TPMS system, the car can identify the specific tire and Canadian M3s cannot do this.

But, yes, we do have a tire pressure monitoring system but it is very different than what our US cousins have.

Ahh, I understand now. Thanks for your clarification
