The bill covers only outward-facing cameras, not cameras inside the cab, addressing privacy concerns raised in committee.
Here's the bill (emphasis added).
"dashboard camera" means a recording device that is capable of continuously recording the view of the road in front of a commercial vehicle through the commercial vehicle's front windshield at all times when the commercial vehicle is operating, and meets the following criteria:
(a) retains at least 72 hours of recording;
(b) records at a minimum video format of high-definition video at a resolution of 1080p;
(c) has night vision capability;
(d) records at the manufacturer's default settings on the device's local storage;.
...
Any recording made by a dashboard camera must be collected, used, disclosed, retained and destroyed in accordance with all applicable privacy and security requirements, including the Personal Information Protection Act.

What you're forgetting is that provincial governments blaming the feds for problems in their own jurisdictions are also two great flavours that go great together.
