We already have the Compass system on a number of 400 series highways and at a regular camera replacement interval purchase high resolution cameras capable of capturing a license plate number. Or set up a trial in an area of the 401. Or contract out to private sector and pay for system through fines generated. Lots of options vs. doing nothing.
Problem is, of course, that just about everything the government touches turns to s..... We have passport issues, CRA can't manage COVID payment issues, submarines spend 95% of the time in drydock, tanks that don't run, subways and LRT's projects that are years behind schedule and double, triple original cost. I'd be challenged to name a government program / project that runs well or is on time, on budget and where the finished product / service works as intended. Compounding this, there is just about zero accountability in government. No consequences when you screw up.
