Courier Shipping Prices - Canada Vs USA

Would someone care to explain why some courier companies charge extra for shipping to Canada from the USA?

I mean, yes, it is a separate country, but lets say for example you are shipping from NYC to Montreal. It is less than a 6 hour drive.

Compare that to the price of shipping from NYC to Las Vegas - which is a 37 hour drive.

Logically you would think that shipping from NYC to Vegas should cost roughly 6 times as much to ship a package to - because it is 6 times further away.

But no, depending on the courier company, it costs more to ship to Montreal simply because it is inside Canada.

So the question then becomes WHY?

Is Canada charging a fee for packages entering the country? Nope.

Is the Canadian version of the courier company more expensive? Nope.

Do Canadian workers get paid more? Possibly, but that shouldn't reflect on the end cost.

The only real explanation that I can come up with is that some courier companies are gouging customers and charging more to ship to Canada simply because they can. Don't like it? Hire a different company.

If you know of a courier that is gouging customers for shipping to Canada please mention them in the comments below.
