I understand that the examiners are the registry places are doing a decent job - the issue is with driving schools that also administer tests - it seems many of them are simply selling licenses without any training or real driving test.
Except for Ontario, there is no requirement for Class 1 drivers to have ANY training, and the road test is a joke. Alberta is taking action, but I don't think any other provinces are planning on making changes. A significant number of fatal crashes involves transport trucks.
