Your post is a little cryptic, but I think you're referring to the fact that Canadians listing on the .com site now have the option of choosing flat-rate shipping options that are more specific to Canada, rather than having their shipping method described as being "from an international location". See this thread:

If you don't think the flat-rate descriptions for Canadian shipments are an accurate reflection of your shipping time, continue to use the "from an international location" options for your flat-rate shipping methods.
At the very least, however, you may find it useful to change your flat-rate shipping method/timeframe descriptor for shipping within Canada.
