I’m originally from eastern canada. They have completely eliminated local transmission. And they have truck drivers bringing in goods, including from the US.

Haven’t heard of it as a source of transmission. Truck drivers generally don’t get off their shift and then go sing karaoke.

And I live now in Quebec, which got local transmission down to almost nothing. But then they opened bars for three months. I think if they had kept them closed a month longer and told the pop “get to zero and we can have a normal winter” we could have done it. Now we’re surging again.
