That's Canadian for, 'right on.'
I will never forget a bill board I saw in NW Ontario. It was a hand with a cigarette between the fingers, and the caption, "Eh."
For those of us in the US, imagine a hand with a Winston, and a pack of Winstons, with the smoke curling up from the lit ash, and the caption, "Yeah."
If I'd had any sense at all, I would have gotten lost in the woods and never managed to find my way home from Kenora. Perhaps Canadian smokes had something to do with it. I never cared for them.
