A sly tweet from a suspended former Conservative senator has triggered a New Democrat MP to call on the federal ethics watchdog to investigate Public Works Minister Diane Finley over what he describes as a "potential pattern" of breaking conflict of interest rules.

On Tuesday night, just hours after Ethics Commissioner Mary Dawson had released a report that found Finley had breached the Conflict of Interest Act by circumventing the standard approval process to give more than a million dollars in federal funding to a Markham-based community centre, suspended Senator Patrick Brazeau took to Twitter to accuse the minister of practising similarly questionable politics in Pontiac during the last election:

1/2 St-Jean Bosco Centre in Maniwaki were promised funds but when former Minister Lawrence Cannon lost in the last election, <a href="https://twitter.com/hashtag/cdnpoli?src=hash">#cdnpoli</a> —@senatorbrazeau

2/2, Finlay pulled funding b/c NDP won election in riding. I met with both Finlay and Wright on this file. Now we all know why. <a href="https://twitter.com/hashtag/cdnpoli?src=hash">#cdnpoli</a> —@senatorbrazeau

"St-Jean Bosco Centre in Maniwaki [was] promised funds but when former minister Lawrence Cannon lost in the last election, Finlay [sic] pulled funding b/c NDP won election in riding," he tweeted.

"I met with both Finlay [sic] and Wright on this file. Now we all know why."

That was enough to pique the interest of Pontiac New Democrat MP Mathieu Ravignat, who beat Cannon in 2011.

NDP MP 'extremely disturbed' by allegations

In a letter sent to Dawson on Wednesday, he says that he was "extremely disturbed" by the findings in her report on Finley's actions with regard to the Markham centre.

"Fifty thousand dollars ended up misspent on this project until it collapsed under the weight of its deficiencies," he noted.

Patrick Brazeau may be suspended from the Conservative caucus, but he's still on Twitter and used the social media platform Tuesday to fire off an allegation about his former colleague Diane Finley. He claims to have participated in meetings about a Maniwaki funding decision as the region's Senate representative. (Sean Kilpatrick/Canadian Press) "Mr. Patrick Brazeau has publicly alleged that Minister Finley also politically interfered into the funding of the Jean Bosco Centre in Maniwaki," the letter continues.

"He claims that they were promised funds, but when former minister Lawrence Cannon lost the last election that Minister Finley pulled the funding. Mr. Brazeau also claims to have met with both Minister Finley and ex-chief of staff at the PMO Nigel Wright to discuss the matter."

If true, Ravignat asserts, "I believe that these actions could have violated sections 4 and 6 of the Conflict of Interest Act," which deal with the prohibitions against furthering private interests and conflict of interest.

"I ask that you investigate these matters and look forward to your response," the letter concludes.

Ravignat also raised the matter in the House of Commons.

"In my own riding in a tweet from former Conservative Senator Patrick Brazeau, it is being alleged that the minister of public works pulled funding from the Jean Bosco Centre in Maniwaki because 'the NDP won the election,'" he told the House during question period on Wednesday.

Centre 'did not merit' grant: Poilievre

"How can the prime minister endorse such unacceptable and unethical behaviour from the minister and the cabinet?" Ravignant asked.

Although Finley had responded directly to earlier questions on the commissioner's findings, Employment Minister Pierre Poilievre took Ravignat's question.

"External and internal assessments showed that the Centre Jean Bosco did not merit a grant of this nature," he told the House.

Rabbi Chaim Mendelsohn successfully lobbied for funding from then-human resources minister Diane Finley's department in 2011. Her decision to fund the project was condemned by ethics watchdog Mary Dawson Tuesday. (CBC) In her report, Dawson concluded that Finley's decision to provide funds to the Markham project contravened the section of the act that prohibits public office holders from making decisions that "they know, or reasonably should know, would place them in a conflict of interest."

"I found that the Markham proposal clearly received preferential treatment," Dawson said.

She also noted that Finley had violated several guidelines, including the Treasury Board’s policy on transfer payments and the prime minister’s guide to accountable government for cabinet ministers.

But she cleared the minister of violating the conflict of interest provisions, as she said the preferential treatment did not appear to be based on the identity of the Markham project's sponsor, Canadian Federation of Chabad Lubavitch director Rabbi Chaim Mendelsohn.

It will be up to Dawson to conduct a preliminary review to see if there are grounds to launch a formal investigation based on Ravignat's complaint.

In the meantime, NDP ethics critic Charlie Angus gave notice Wednesday of the following motion to be debated and voted upon at the next meeting of the Commons ethics committee, expected later this month:

That pursuant to Standing Order 108(3)(h), the committee undertake a study on the report of the Conflict of Interest and Ethics Commissioner entitled: The Finley Report March 10th 2015; that the committee include in its study the Prime Minister’s guidance document to Ministers, Ministers of state, and Parliamentary secretaries; that the committee include in its study broadening section 7 of the conflict of interest act; that the committee invite as part of the study the Conflict of Interest and Ethics Commissioner of Canada, MP Peter Kent, MP John Baird, Minister Finley, PMO Chief of Staff Ray Novak, Nigel Wright, Rabbi Mendelsohn, and Mr. Paquette who was the Senior Assistant Deputy Minister at HRSDC; and that the committee report its findings to the House.
