Err Umm...
Such an issue is not shown in the
2007 Canada Stamp Program as listed at:-
http://www.rpsc.org/canadapost.htm
but....
Issue dates are subject to change by Canada Post
Nor is there any reference on that pages linked news page and as it is The Royal Philatelic Society of Canada's site you would expect them to know
As should the Canada Post/Postes. on line shop at:-
http://www.canadapost.ca/personal/co.../default-e.asp
but to check I had to register (along with millions of others creating a log-jam until tomorrow!)!

I suspect that what your friend heard was that CHar was trying to raise some funds by selling her stamp

at least I think that is the one of two that Char bought back in November
Addendum i see in that canada.com article that the stamps will be 52 cent denomination not 8
