Conservatives warn Bernier not to use party member list from his leadership bid

The Conservative Party machinery isn't letting rogue MP Maxime Bernier leave with any party favours.

The Tories' lawyers sent Bernier a letter Tuesday warning him not to use any party member listsa valuable tool for fundraising and speaking directly to activistsnow that he's left the party.

Radio-Canada, CBC's french-language arm, obtained a copy of the letter. In it, lawyer Arthur Hamilton, counsel for the Conservative Party of Canada and theConservative Fund Canada, asks Bernier to return any lists he received, maintained and supplemented during his leadership run.

Hamilton also asks Bernier to confirm he didn't consult any such lists when he announced he'd be leaving the Conservative banner to start his own national party late last week.

"We require immediate notification of the circumstances of such use, and the full scope and particulars of what exactly that use entailed," reads the missive.

"You are hereby advised that we take all necessary steps to protect the personal information and privacy of our members and donors."

A source close to the Bernier , who spoke on the condition of anonymity, called the letter "an intimidation attempt" and said the Quebec MP returned his list of party members at the end of the leadership race.

Thesource also told Radio-Canada that Bernier has about 30,000 addresses through his own website, which uses NationBuilder to manage his database.

"All the addresses we have, have been collected separately," said the source.

Battling the party

He said he had to leave because his former party is "too intellectually andmorally corrupt to be reformed,"and underScheer's leadership, it has failed to stand up for conservative principles like dismantlingsupply managementand opposing retaliatory tariffs in thetrade dispute with the U.S.

The plan, saidBernier, is to have the federal party upand running in two to three months.

While he isn't expecting anyone from his old party to quit the caucus and help him start a new one, he told CBCNews that since he announced his departure some 500 people have called him.

Another former leadership hopeful, Saskatchewan MP Brad Trost, is entangled in his own legal battle with the party over the membership lists.

The Conservative Party determined that Trost's leadership campaign leaked a copy of the party's membership list to a firearms rights group and levied $50,000 fine against his campaign.

The Conservative Party uses a practice known as "salting" to trace leaks of its membership list. Each leadership campaign received a slightly different copy of the list to allow officialsto trace back unauthorized releases.

Trost has insisted no one from his team was responsible and has threatened in the past to take his battle "all the way" to the Supreme Court.
