[Tweet at 1842 Sunday night] Some posters mistakingly believe that western embassies are sheltering wounded protestors in Tehran, except Canada. I've looked into this ...

A parallel path followed with urgency can bring the already built MAPLE reactors to an operating state or perhaps the next six to eighteen months. And such a strategy offers the best prospect for putting Canada on a firm footing for assurance of supply.[of medical isotopes] ... there are two MAPLE reactors, each with the capacity to deliver more than the current world requirement. Positive PCR requires a relatively simple engineering fix to restrain the bowing of the elements and to reduce the PCR to approximately zero. I thank you for your attention, and I hope this doesn't turn into another Avro Arrow.

The engineering team that built the MAPLE nuclear reactors at Chalk River, Ont., was four months away from fixing a technical problem that had kept them from getting a licence when the project was cancelled, MPs were told Thursday...

If you want to see what official Ottawa is doing on Twitter, I'm trying to maintain a directory of what I call Political Twits. It ain't pretty, but there you'll find the Twitter handles of any MP I find on Twitter, any Parliament Hill staffer, Hill journalist, or Hill hanger-on. You'll also find a links to institutions in official Ottawa -- the Canadian War Museum is a good example -- as well as any hashtag I can find or create associated with the work of the federal government. My directory is not for people talking about federal politics, it's a directory of the people actually engaged in federal politics -- the primary sources. As it says on the home page of that directory, if you've got something send it along.

In 2005, Jack Layton won $4.6 billion in new investments in housing and transit in exchange for supporting the minority government of Paul Martin. In 2009, Michael Ignatieff got a working group and an opposition day for supporting the minority government of Stephen Harper.

This just in from the Liberals, spelling out the deal that has been struck. One key to note -- Liberals get a chance in late September to table a non-confidence motion so if they want a fall election, that will give them the opportunity. Otherwise, Liberals would not have had that chance until the fall:

Flaherty insists once normal growth resumes, tax revenues will naturally rise even as the extra spending required during a recession eases and that will let the government of the day balance the budget without tax increases or spending cuts. The government predicts a balanced budget by the end of 2014, a forecast Flaherty stuck to Tuesday. The Liberals say he's dreaming.

The chief executive officer of Nortel Networks Corp., has been summoned to appear before a House of Commons committee Thursday to explain how he and other senior managers qualified for millions of dollars in bonus payments as pensioners and employees were having their benefits cut or delayed while the company restructures under bankruptcy protection.

But Christopher Heysel said a speedy transformation of the McMaster reactor from a multi-purpose research machine to a high-volume isotope producer needs co-operation of other "stakeholders," including Atomic Energy of Canada Ltd., the federal government and the nuclear safety regulator. The transformation would be relatively cheap as well, just $30 million over five years, Heysel said.

Raitt: "You know what solves this problem? Money. And if it’s just about money, we’ll figure it out."

How much would it cost to fix the MAPLEs?

AECL: All in, the cost was in excess of $1 billion.
