It turns out there are benefits to being age 65 -- other than cheap movie tickets. Starting at age 65 (and every five years after that) you can get an official birthday greeting from the Prime Minister of Canada, the Rt. Hon. Paul Martin.
The Office of the Prime Minister will send you an official letter from the PM (complete with a gold sticker!) for any significant birthday or wedding anniversary. Simply complete the online form and wait a few weeks for mail from Ottawa. Then buy a frame, put it on a wall and impress your friends.
The PMO won't actually try to confirm that you are the age you claim to be. Nor will they request a marriage certicate to see if you and the misses have completed at least 25 years of wedded bliss. So, basically any 15-year-old with access to the Internet can get one.
In case you're wondering, the office of Her Majesty, Queen Elizabeth II requires documenation before sending congratulatory letters. Also, the Queen only send letters to subjects on their 100th birthday.
