This handy sheet gives the current Canada Post and USPS postage rates for basic letters between the USA and Canada. I've exported the spreadsheet as an easily printable PDF file. Print it out for a handy quick reference card, which you can keep next to your stamps or your postage scale. You can also modify the source spreadsheet.
