I think we do it right in our province.
In Ontario once you turn 80, you need to renew your license every 2 years and go through an assessment process that could include a road test......from what I understand a fair number of drivers just give up and don't keep their license, rather than go through it.
If you are 80 years of age or older, you are required to renew your driver’s licence every two years. This renewal process helps keep seniors mobile and independent longer, while helping to ensure that unsafe drivers are identified and appropriate actions are taken.
You need to undergo a driving-record review, complete a vision test and participate in a 45-minute group education session, followed by an in-class screening component. The in-class screening component will help better assess your fitness to drive.
You may be required to pass a road test before being able to renew your licence, or you may be able to renew but will have to follow up and submit medical information. The driver improvement counsellor at the group education session will discuss this with you.
There is no charge for any of the licence-renewal requirements. You only have to pay the licence-renewal fee.
