There should be a UV barcode on the bottom of the back of the envelope with the date JA>> and a letter for the postal code of the sorting plant that first received this envelope when it came into Canada.
Also should be a bar code on the bottom of the front with Bee See's postal code in bar code form.
All this doesn't give the year (if it is there) but it's a start and a help. Annoying to not have a readable cancel anywhere though.
I had just mailed 7 envelopes to myself to get cancels and they came to me with the UV bar codes in great shape front and back but no readable cancels. I think
Canada Post has temporarily run out of ordinary ink.
For Bee See's cover above you would hope to have a cancel from Great Britain on there somewhere.
They all seem to be concentrating on the delivery on the mail and not the cancelling of the stamps. Maybe they figure they can't win and have just gone to charging more for stamps and services to make up the projected loss of reused postage by some un-named souls.
