There is an international committee being run out of the United States, of which Transport Canada is a member, looking at original equipment manufacture of these devices. A couple of manufacturers are also working on these technologies, but they're still a number of years away.
The other thing to consider is that once you have the device, it would take roughly 11 years to roll over 80% of the fleet. The people who would make use of these the most are probably the ones least likely to get new cars, so it would be a long time before those people would be exposed to that device. That may be a long-term solution, but not necessarily a short-term one.
