Green Party Leader Elizabeth May took to Twitter Thursday to attack the NDP for heckling her into silence.

May was shouted down during debate on an Opposition Day motion from NDP Leader Thomas Mulcair calling on Prime Minister Stephen Harper to meet with premiers to discuss the economy.

After Mulcair had spoken on the ongoing cost to clean up the Sydney tar ponds, May asked the NDP leader about whether his party intends to do something to combat climate change.

"I would like to ask the leader of the official opposition if, in his comparison between trade deficits and ecological deficits, he would advance the need to actually do something about the climate crisis rather than point fingers back and forth across the aisle," May said.

"The previous Liberal government had a plan in place. It would have reduced emissions. It would have..." May was stopped by NDP heckles before she could finish her question. She then sat down saying she could not be heard.

New Deputy Speaker Joe Comartin then gave the floor back to Mulcair rather than silencing the House and allowing May to finish her question. Something May would tweet about later.

It was May's first tweet, however, that sparked a firestorm online: "There's a first. I couldn't finish my question due to heckling from the NDP. So much for Jack Layton's call for civility."

The post has been retweeted well over 100 times, including by Liberal MP Justin Trudeau. The Liberal Party's account also chimed in support for May, as did Grit MP Carolyn Bennett.

May went on to tweet that "Usually when I sit down due to being heckled, the Speaker calls for order. New Deputy Speaker and it didn't happen." She would later temper her criticism of Comartin, tweeting: "I think the new Deputy Speaker is finding his feet."

May also spared the NDP's environment critic Megan Leslie from her critique, posting that "I doubt very much Megan was yelling. The noise was mostly male voices. It was clearly most of NDP caucus. Not all."

The Green Party leader has long supported co-operation between the NDP, Liberals and her own party.

In 2007, May signed a non-aggression pact with the Liberals ahead of the 2008 election. The Liberals, then under Stephane Dion, agreed not to run a candidate in the riding of Central Nova where May was attempting to unseat then-Conservative Foreign Affairs Minister Peter MacKay and the Greens did not run against Dion in his Montreal riding of Saint-Laurent-Cartierville.

Then-NDP leader Jack Layton refused a similar deal with May.

That didn't stop the Green Party leader from supporting the NDP, along with the Liberals and Bloc Québécois, during the coalition crisis of 2008. In fact, May even said she had discussed a possible Senate appointment for herself with Dion.

Despite past co-operation, May ruled out a merger with the NDP and Liberals in 2011, arguing the Greens are simply too different from the more mainstream parties.

Perhaps this latest incident will put any doubts about that decision to rest.

    Besides tweeting at a furious pace, former astronaut and current Liberal MP <a href="https://twitter.com/#!/MarcGarneau" target="_hplink">Marc Garneau</a> can be seen regularly carrying on conversations with other users.

  • 9. Olivia Chow

    With more than 17,000 followers, Olivia Chow doesn't need our help. But we love her tweets, especially the funny ones. This <a href="https://twitter.com/#!/oliviachow/status/198021722232979457" target="_hplink">Rob Ford zinger stands out</a>: "Dear journalists, the lilac tree in front of my #Toronto house is in bloom, come and take a photo by the fence, I won't call 911." (CP)

  • 8. James Moore

    Another Tory minister who bucks his party's Twitter trend is <a href="https://twitter.com/#!/JamesMoore_org" target="_hplink">James Moore</a>. His account shows all the usual signs of engagement, but to be perfectly honest it was the <a href="https://twitter.com/#!/JamesMoore_org/media/grid" target="_hplink">cute photos</a> of his <a href="https://twitter.com/#!/JamesMoore_org/media/slideshow?url=pic.twitter.com%2FrFgZ2LPR" target="_hplink">two dogs</a> that secured his spot on the list. (CP)

  • 7. Megan Leslie

    NDP MP <a href="https://twitter.com/#!/meganlesliemp" target="_hplink">Megan Leslie</a> has one of the most active accounts in Parliament. Our favourite tweet in recent months? "Finally found a parking spot in Whitehorse. No need to call Bev Oda's driver. http://yfrog.com/nwtxmtzj" (CP)

  • 6. Peggy Nash

    Unlike <a href="http://www.huffingtonpost.ca/2012/05/09/worst-mps-twitter-canada_n_1504199.html?ref=canada-politics" target="_hplink">Thomas Mulcair, who has stopped tweeting</a> since the end of the NDP leadership contest, <a href="https://twitter.com/#!/PeggyNashNDP" target="_hplink">Peggy Nash</a> continues to post up a storm. Her appearance on this list also has a lot to do with her <a href="https://twitter.com/#!/PeggyNashNDP/status/197057876865454081" target="_hplink">recent allusion to the cartoon "South Park."</a> (CP)

  • 5. Justin Trudeau

    What can you say about <a href="https://twitter.com/#!/JUSTINPJTRUDEAU" target="_hplink">Justin Trudeau</a>? He's the rock star of Canadian politics and his Twitter stats show it. More than 130,000 followers and a verified check mark -- the surest sign of an online celeb. And while <a href="http://www.huffingtonpost.ca/2012/03/13/justin-trudeau-blackberry_n_1342509.html" target="_hplink">HuffPost got into a minor tiff with Trudeau over a tweet</a> he sent out earlier this year about his BlackBerry, we're still big fans of the Liberal MP's stream. What other Canadian politician would have the guts to tweet a photo like <a href="http://twitpic.com/3aqlx9" target="_hplink">this</a>. (CP)

  • 4. Jason Kenney

    <a href="https://twitter.com/#!/kenneyjason" target="_hplink">Jason Kenney's Twitter stream</a> often resembles a travel journal. The Immigration Minister spends a lot of time travelling the country and it shows in his feed and photos. Something else we've learned from following Kenney? <a href="https://twitter.com/#!/kenneyjason/media/grid" target="_hplink">He loves purple ties</a>. (CP)

  • 3. Tony Clement

    Alright, we know we already put <a href="https://twitter.com/#!/tonyclementcpc" target="_hplink">Tony Clement</a> on our <a href="http://www.huffingtonpost.ca/2012/05/09/worst-mps-twitter-canada_n_1504199.html?ref=canada-politics" target="_hplink">worst MPs on Twitter list</a>, but we do have a love hate relationship with the Tory minister. While his tweets have grown less interesting since <a href="http://www.huffingtonpost.ca/2012/01/10/tony-clement-jackass-twitter_n_1196261.html" target="_hplink">Jackass-Gate</a>, Clement is still miles ahead of most MPs when it comes to using social media. No wonder he's been<a href="http://www.canada.com/news/Tony+Clement+vows+innovative+open+government+critics+point+poor+record/5940420/story.html" target="_hplink"> tasked with leading the Conservatives' Open Government initiative</a> to put more federal info online. (CP)

  • 2. Bob Rae

    'Interim' Liberal Leader Bob Rae may not have captured his party's permanent top job yet, but he definitely hold the attention of his Twitter followers. All 26,000 of them. He gets in on <a href="https://twitter.com/#!/bobraeMP/media/slideshow?url=http%3A%2F%2Fyfrog.com%2Fh03w0bmj" target="_hplink">photo meme action</a> and <a href="http://www.huffingtonpost.ca/2011/12/14/bob-rae-twitter-bs-young-liberals_n_1149155.html" target="_hplink">isn't afraid to use colourful language</a>. <a href="http://www.huffingtonpost.ca/2012/05/09/worst-mps-twitter-canada_n_1504199.html?ref=canada-politics" target="_hplink">Compared to the accounts of fellow leaders Thomas Mulcair and Stephen Harper</a>, an absolute gem. (CP)

  • 1. Elizabeth May

    She may be the leader of the smallest party in Parliament, but <a href="https://twitter.com/#!/elizabethmay" target="_hplink">Elizabeth May</a> punches way above her weight online. The Green Party leader has nearly 40,000 followers, roughly triple the count held by <a href="https://twitter.com/#!/thomasmulcair" target="_hplink">Thomas Mulcair</a>. How did she become such a digital success? One word: engagement. May's stream shows consistent interaction with followers and journalists. The leaders of the larger parties could learn a thing or two from this plucky underdog. (CP)

    The <a href="https://twitter.com/#!/mpPeterKent" target="_hplink">Minister of the Environment Peter Kent</a> last tweeted back in January, despite the flurry of coverage regarding his portfolio in recent months. On the plus side, he has posted plenty of photos, although most are of the MP smiling with constituents variety. (CP)

  • 9. Dean Del Mastro

    The parliamentary secretary to the prime minister and <a href="https://twitter.com/#!/DeanDelMastro" target="_hplink"> Minister of Intergovernmental Affairs Dean Del Mastro</a> has a classic ghost-town account: Five tweets back in 2009 and then silence. (CP)

  • 8. Vic Toews

    <a href="https://twitter.com/#!/toewsvic" target="_hplink">Minister of Public Safety Vic Toews</a> is actually relatively active on Twitter compared to his cabinet colleagues. Toews makes the list due to his role in promoting the government's online spying legislation, <a href="http://www.huffingtonpost.ca/2012/02/16/vic-toews-youtube-vikileaks-twitter_n_1281633.html" target="_hplink">a role which earned the minister heaps of scorn on the social network and sparked the #TellVicEverything and #DontToewsMeBro hashtags</a>. (CP)

  • 7. Peter MacKay

    <a href="https://twitter.com/#!/mackaycpc" target="_hplink">Defence Minister Peter MacKay</a> hasn't tweeted anything to his more than 3,000 followers since May of last year. (CP)

  • 6. Charlie Angus

    <a href="https://twitter.com/#!/charlieangusmp" target="_hplink">NDP MP Charlie Angus</a> was one of the most active MPs on Twitter. That is until he got sick of all the negativity and <a href="http://www.huffingtonpost.ca/charlie-angus/quit-twitter_b_1394617.html" target="_hplink">publicly announced he was leaving the social network</a>. His account is still online, so it's still possible he'll make a comeback. (CP)

  • 5, Nycole Turmel

    "Thomas Mulcair just gave an inspirational speech at the Economic Club of Canada luncheon!" This is what you can come to expect from the <a href="https://twitter.com/#!/nycole_turmel" target="_hplink">former interim leader of the NDP Nycole Turmel</a> on Twitter. Her stream is dominated by posts about appearances and press releases. She rarely interacts with other users and seems to be slowing down her usage since the NDP leadership race ended and she was replaced by Thomas Mulcair. (CP)

  • 4. Tony Clement

    This is the controversial one. <a href="https://twitter.com/#!/tonyclementcpc" target="_hplink">Treasury Board President Tony Clement</a> is notorious in Ottawa and beyond for his regular use of Twitter. So why does the poster child for Canadian politicians on social networks make the list?<a href="http://www.huffingtonpost.ca/2012/01/10/tony-clement-jackass-twitter_n_1196261.html" target="_hplink"> It goes back to an incident last year in which Clement called a teen a jackass in a tweet after being corrected on a spelling mistake</a>. Clement apologized and ever since his account just hasn't quite been the same. The humour which once made the account one to watch seems to be gone. (CP)

  • 3. Daniel Paillé

    The <a href="https://twitter.com/#!/danielpaille" target="_hplink">Leader of the Bloc Québécois Daniel Paillé</a> has sent out just 89 tweets since joining in October of 2011. Despite being a federal leader not one of those 89 has been in English. (CP)

    We at HuffPost have regularly been checking <a href="https://twitter.com/#!/thomasmulcair" target="_hplink">NDP Leader Thomas Mulcair's Twitter account</a> in the hope that he'll actually start using it. Since winning the leadership back in March, the account has gone completely silent. Previous to that it was extremely active. What gives? (CP)

  • 1. Stephen Harper

    With such a large staff, you would expect the prime minister to be a little more consistent with his use of Twitter. Stephen Harper's account has sent out just 12 tweets so far in 2012, many of them linking to press releases. With nearly 220,000 followers, the PM is missing out on an excellent opportunity to sell himself and the Conservative brand. Harper should take a page out of <a href="https://twitter.com/#!/BARACKOBAMA" target="_hplink">Barack Obama's playbook</a>. At the time of writing, the U.S. president had posted 14 tweets in just the last 24 hours. Obama even signs tweets that come directly from him. Come on Stephen, we don't need the Americans to be better than us at anything else. (CP)
