I don't know if it's true for Canada, but UPS and FedEx are both changing how shipping costs are calculated here in the US. You should check with UPS Canada to verify if they have changes.
>I am working with the UPS C# samples for the Web Service and, among several samples, only C# is available for .NET so I have to do a little bit of work to convert and adjust as needed. That company really offers a great set of tools to negotiate with everything in regards to a shipment.
