I don't really see how the Highway 17 situation is unique in the context of winter storms though. As per the comment above this, most transit of East and West goods occurs via other means, meaning the Highway 17 bottleneck is hardly some vital artery. A winter storm shutting down Highway 401 for example is much more economically chaotic, and has the practical impact of making travel through its corridor impractical (and in some circumstances just as impossible as if it were a single bottleneck). This scenario does periodically happen, and people manage just fine since the closures are expected to be short-lived.

So I don't buy the argument that Canada needs the US because of the threat of transit networks being completely cut off. I am much more amiable to the argument that reciprocal road tolls like this would be stupid because they'd increase the cost of goods for all of us (Canadians and Americans alike). As noted earlier, the fastest route between East and West is through the US due to geography. But or course things like this are stupid, and I doubt an argument as to why is required here. Maybe we should pull back and stop doing all this nonsense like arbitrary tariffs on close allied nations? Especially those who's explicit purpose as described by the elected head of state is to threaten the sovereignty of the other?

My only point was that Canada has more to lose than the US if we start taxing journeys through each others countries. A lot of commenters missed that.

Your point is terrible though. How many people live in Kenora? 15,000? There's not a highway of trucks that are backed up from Kenora, anything that needs to be transported to Winnipeg will come from the West coast, and anything to Toronto will come straight down the St.Lawrence.
