It certainly looks like CSIS Director Dick Fadden was bang on about foreign influence in Canada. The Iranian embassy in Ottawa provides a prime example and I’ll wager the intelligence service prompted the threats mentioned below. Terry Glavin tells the story, which is still developing (some links added):

The National Library capitulates to Iran’s bullies
When federal Cabinet Minister James Moore intervened Tuesday to protest the cancelled screening of the film Iranium at the National Library and Archives in Ottawa [now officially Library and Archives Canada; under the Liberals the word “national” was removed from several federal institutions, e.g the National Museum of Science and Technology, in order to avoid giving any possible offense to the Québécois I am sure], he said: “I am disappointed that Library & Archives Canada chose not to show the film tonight due to threats of violence. . . The Iranian Embassy will not dictate to the Government of Canada which films will or will not be shown in Canada.”
But the screening ended up cancelled anyway after a “suspicious package” shut down the Library. Ottawa police and a haz-mat team showed up late in the afternoon and the staff was sent home. In another version of events, most employees were already gone when suspicious letters were dropped off at the building, on Wellington Street, by a man who hurried away.
Altogether it’s been a busy couple of days for my pal Fred Litwin, who runs Ottawa’s Free-Thinking Film Society, the host of the event. Fred’s been keeping me posted – I’m a director of the society (and no, I’m neither “libertarian” nor “conservative”). Only two months ago I joined some Iranian comrades at the National Library to give a talk at a Film Society screening of another film about Iranian despotism, The Stoning of Soraya M.
The Iranian embassy confirms it was involved in the initial “complaints” about the Iranium event. The Library confirms the embassy lodged a formal request to cancel the screening. A “suspicious” package or a letter that turned out to be a false alarm – that’s something I can understand as a justification for cancelling the showing. But the National Library first cancelled the screening after merely having received “complaints.” It agreed not to back down to the protests, only after Moore’s office intervened. But then the Library apparently backed down again after “letters” and “threats” and “protests,” or something.
“I’m outraged that in the capital of Canada the Iranians have been able to shut down a movie,” Fred said. “Bad enough in Tehran, but in Ottawa?”
Apparently so. Something very nasty is going on here, and I am more than a little curious to discover what’s at the bottom of it, who was involved in these “protests,” and what the hell the National Library was thinking by cancelling the screening in the first place. The National Library is not the Bijou. It’s a venerable, national, public institution. Iranium is an important film, it’s a new film, and Clare Lopez, a Middle East strategic policy and intelligence expert was flown in from Washington D.C. for the planned screening. The National Library owes more than an apology and a lot more than full compensation for the Film Society’s costs. It owes every Canadian a complete explanation and full accounting of what the hell just happened.

I imagine it was Ms. Lopez the Iranians really wanted to muzzle seeing as the film will be widely available soon. Have a listen to her here at CFRA Ottawa’s website:

Clare Lopez with Nick Vandergragt
As mentioned by Lowell Green, here is the program that originally aired Thursday January 6th with Nick at Night filling in for Lowell with special guest Clare M. Lopez, a strategic policy and intelligence expert with a focus on Middle East, national defense, WMD, and counterterrorism issues. They were discussing “Iranium”, a film that details the brutal nature of the Iranian regime to its own citizens, and the Iranian people’s desire to rejoin the international community.
The planned screening of Iranium was cancelled at the Library and Archives Canada building Tuesday night due to protest threats.

Ironically, the Iranian Embassy itself has apparently rented the theatre at the Archives several times to show its own propaganda films.
The government has now responded pretty firmly, effectively it appears instructing the Archives to let the film be shown. From Giggles Taber of the Globe, who seems to see the story only in party political terms–missing herself as usual any bigger picture:

Top Tories bristle at Iranian [sic] film’s cancellation
…Tehran’s atomic ambition. Two senior Harper cabinet ministers are criticizing the cancellation of a documentary film that looks at Iran’s ability to build nuclear weapons, calling it “outrageous” and warning the Canadian government will not be bullied by Iran.
Immigration Minister Jason Kenney and Heritage Minister James Moore weighed in on the controversy via Twitter as news broke that the film, Iranium, would not be screened.
Calling the cancellation “outrageous,” Mr. Kenney said: “I hope that folks from across the political spectrum will help the Free Thinking Film Society to overcome intimidation & screen the film.”
The Free Thinking Film Society organized the event Tuesday at the National Archives of Canada. It was called off, according to reports, after threats of protests were made by phone and suspicious letters were dropped off at the venue. The Iranian embassy also filed a formal complaint, saying it wanted the showing stopped.
This did not impress the Heritage Minister. Mr. Moore cautioned the Iranian Embassy not to “dictate to the Government of Canada which films will or will not be shown in Canada.”
He added: “I am disappointed that Library & Archives Canada chose not to show the film tonight due to threats of violence,” wrote Mr. Moore…
Update Mr. Moore says the show will go on.
According the his press secretary, Mr. Moore started working on figuring out how the issue could be corrected as soon as heard the screening was in doubt. He has since instructed the Archives to honour its commitment to show the film while taking all appropriate steps to ensure security, Codie Taylor said.
“Canada does not accept attempts from the Iranian Embassy to dictate what films will and will not be shown in Canada,” the Heritage Minister said through Ms. Taylor. “The principle of free speech is one of the cornerstones of our democracy”
