L is for learners, you must have a fully licensed person over 25 yrs old in the car. Unlimited passengers as long as you have a fully licensed person over 25 with you. You can take your N (New) exam a year later (I think), by passing that, you can drive alone with up to one unrelated passenger and unlimited immediate family members. If you have a fully licensed driver over 25 yrs with you, you can drive anyone. And then you get your class 5 (normal drivers license, goes up to 1 which I think is ambulance), which means you're unrestricted essentially for typical driving. No motorcycles, airbrakes, etc yet.
I think what doobies42(0) was getting at, now again this is just a guess, is that it's ironic that Americans would say EH? if they added an 'A' to Okanogan. I think the irony he is going for is that of an American saying a stereotypical Canadian slang. I'm not an English student, so I really couldn't tell you if that is irony, but I do think thats what he was getting at.
