Admiral told a friend he was 'exhausted' by internal shipbuilding battles

The military's embattled second-in-command considered resigning when he was head of the Royal Canadian Navy, over what he perceived was political interference from the newly elected Liberal government, CBC News has learned.

Vice-Admiral Mark Norman's frustration hit the boiling point during one weekend in late November 2015, days after a series of leaks about the troubled national shipbuilding program.

He confided to a friend that he was "exhausted" by the internal political, bureaucratic and corporate battles; that he was "prepared to go public, if necessary;" how he couldn't "keep playing along much longer" and he was "prepared to resign over this," sources told CBC News.

The focus of his frustration related to a cabinet decision temporarily halting the planned lease of a much-needed navy supply ship from Levis, Que.-based Chantier Davieshipyards.

Just days before the pause was ordered, the co-CEO of rival Irving Shipbuilding,James Irving,sent a letter to Public Services and ProcurementMinister Judy Foote and Defence Minister Harjit Sajjan. It was also copied to Treasury Board Presidentand Nova Scotia MPScott Brison and Finance Minister Bill Morneau, asking for a review of the lease plan.

All of those details were leaked to the media, setting off a furious round of internal finger-pointing and adding fuel to the fire of an ongoing RCMP investigation into unauthorized disclosures of cabinet documents and decisions.

Suspended but not charged

Norman swallowed his frustration, continued on as navy commander, and was eventually appointed as the vice-chief of defence staff in the summer of 2016 a post he was suspended from in January after the RCMP questioned him about the leaks.

He has not been charged with anything, but remains off duty. His lawyer, Marie Henein, has said he looks forward to clearing his name.

The RCMP, National Defence and the Liberal government have steadfastly refused to comment on the removal of Norman, who is considered by the rank and file to be a straight shooter.

No one from the Liberal government was immediately available to comment Wednesday night.

Norman's boss,Chief of Defence Staff Gen. Jonathan Vance,has publicly said that suspending Norman,a lifelong friend,was one of the hardest days of his career, but that he was required to do so and maintain a dignified silence while events played out.

Vance has not, however, said what his deputy has been accused of doing.

It is unclear what evidence,if any,the RCMP has that Norman was the source of not only the supply ship leak, but a series of other disclosures that embarrassed both the Liberals and the previous Conservative government. Sources have told CBC News the Conservative government initiated the wide-ranging federal police investigation of National Defence.

Wide-ranging investigation

The Mounties were already looking into the leak of a 2014 cabinet decision, whichapproved the sole-source, $800-million purchase of new Sea Sparrow missiles for the frigates, and further disclosuresfollowing the 2015 electionof the military's plans to house Syrian refugees.

But the investigation kicked into higher gear when the story about the pause to the Davie shipyard project appeared on Nov. 20, 2015.

The program,worth about $587 million to taxpayers,was crucial to the navy because it had retired its two supply ships,HMCS Preserver and HMCS Protecteur,without any immediate replacements.

It was eventually allowed to go forward, despite objections from Irving. It had been locked in by the previous Conservative government and would have meant millions of dollars in cancellation penalties.

At the time, the Trudeau Liberals faced a hard contractual deadline of Nov. 30, 2015, for approving the Davie deal.

The pause had the potential of killing the Quebec shipyard because the company's financing was project-specific and up for renewal at the time, sources told CBC News.

Irving denial

In the aftermath of the leaks, angry federal bureaucrats accused Irving officials of slipping the letter calling for a review to reporters at CBC News and Postmedia something the notoriously media-averse company vehemently denied.

Kevin McCoy, president of Irving Shipbuilding Inc., issued a statement at the height of the controversy, noting the company had also been asked to come up with an interim supply ship plan, and their call for a review of their rival's deal was meant to ensure "an open, merit-based evaluation of all proposals."

But how hard the company pushed that line behind closed doors with the new Liberal government is unclear.

Defence Minister Harjit Sajjan, who as the newly appointed minister, toured the Halifax shipyard on Nov. 20, 2015, and met with Irving officials the same day the first of the leaked stories on the Davie supply ship program appeared in the media.

He and other freshly minted Liberal ministers, including Scott Brison, were at the time attending the annual security and defence forum in the Nova Scotia capital.

Sources say the subject of the Quebec shipyard contract came up during the tour of the newly modernized yard and was painted "as a threat to the Nova Scotia economy."

The two journalists who received the leaked Irving letters, which outlined the company's objections, have since been hired by the Liberal government.
