Dear, While I don’t know who you are off hand (and neither does my auto correct), I thank you for this info. I couldn’t find it on the Canada Post website very easily either. Perhaps you made a phone call to your local post office, something we in this digital age don’t think to do first as we now instinctively know takes so very long because we have to wait through a barrage of pre-recorded messages to get any information at all, much less actually talk to a real human being. Again, thanks!
