TIL that the Canadian government will send you a flag that has been flown on top of the Parliament buildings. The current waiting list is over 100 years.
I ordered 2 from the Peace Tower about 5 years back when the wait was 72 years. Had my kids take over their respective “orders”. They just might arrive in time for their grandkids to enjoy them. They are pretty darn big too.
You can also do this with US flags flown over the capitol! It’s usually by accessing your senator’s website (lastname.senate.gov), though it’s definitely not a 100 year wait. I think a lot of states will also do this with your state flag as well (I know mine does, also through my state senator).
