This is already in effect in some states in Australia. In NSW, people above the age of 75 (or if they have a listed medical condition if younger such as diabetes or epilepsy) have to undergo an annual medical and an eye exam as part of the Fitness to Drive assessment. And at certain ages (80 and 85) a medical as well as a driving test.This video popped up on YouTube. Pretty scary for us seniors in Canada, if true. After 70 we will have to take tests and spend a lot of money to prove we can still drive safely. Supposedly starting this month, for over 70s.
Perhaps the prairie provinces will not implement it (wishful thinking?).
I can understand the concept but it’s expensive and nerve wracking for them, and requires so much paperwork for doctors and optometrists.
