As I noted earlier, a press-release was released late last night that was posted here. This looks to be a scan of a faxed press release.
But where did this come from? It is not on letter head (as Mark pointed out in the comments). [see update] Nor is it included on the Conservative Party Press Release page.
If the newsrelease is a fake, then it is possible that the additions discussed earlier (here, here, here, here, and here).
And that would mean that a whole day of conspiracy theorizing is down the pipes!
update In the comments, Mike of Rational Reasons reports
buckets, according to what I heard on the CBC radio this evening at 18:10ish, the memo is genuine in that it originated from the CPC press secretary. He apparently handed it out last night to reporters at a bar they frequent here in town (probably the National Press Club), where he referred to it as a "suicide note"...
update One of the reporters who interviewed me told me that he was there when it was distributed and confirmed that the term 'suicide note' was indeed used. Why is there no header, signature, contact information? Because the scan cut them off.
