A few years ago, I purchased the 2004 and 2005 year sets from Canada Post. Yesterday, I finally looked at the back of the packages as I opened them up and found another addition to The List. The stamp shown here, issued to commemorate Expo 2005 in Japan, was issued on March 4, 2005, according to the year set package.
I don’t have the Scott number for it yet since my copy of volume 2 is the 2006 edition (where the last Canadian stamps listed are from February 2005). Yeah, it’s on my list to update, but I’m still working from the 2002 edition of volumes 5 and 6, so those will be updated first.
