The independent analyst that left her job investigating the Ministry of Transportation now says that staff members filed documents that were falsified.

Annie Trudel was hired by former Transportation Minister Robert Poeti to audit the department.

But after running into multiple battles with personnel -- going so far as to call the actions of Transport Ministry staff "sabotage" -- Trudel resigned from the post in April.

Now Trudel has sent a letter to Parti Quebecois MNA Carole Poirier, the head of the National Assembly committee on public administration.

In that letter, Trudel says she has concerns because of "contradictions" in documents the ministry provided to the committee -- documents that have since been made public.

“I'm thinking that when ministries are sending us a document, it's a real document, it's the truth so I'm very disappointed. But it's an allegation of Mrs. Trudel, so we will verify these allegations,” said Poirier.

Trudel says the documents were not verified by the committee, and she wants the original documents that she prepared herself to be made public, instead of the one "fabricated" by the ministry.

She says there are false statements, erroneous information and irregularities in the documents.

Transport Minister Jacques Daoust said an email shows Trudel invited a ministry employee to make corrections and add comments to her work.

“According to us, there's no fabricated document. Things are not wrong. But if there's something that Mme. Trudel considers is wrong, she should inform UPAC,” he said.

Trudel's letter dominated the first part of question period at the National Assembly on Wednesday, with PQ house leader Bernard Drainville suggesting the Transport Ministry is trying to orchestrate a cover up.

CAQ leader Francois Legault said it's very troubling.

"This morning we understand from Mrs. Trudel that her documents have been changed, so I worry about this and I think we need some answers from Mr. Couillard," he said.

Trudel says all the real, accurate information she collected is on a USB key that's been turned over to UPAC.

UPAC chief Robert Lafreniere said those documents should not be made public, or even made available to MNAs on the public administration committee, but on Wednesday afternoon he changed his mind.

Lafreniere said he would discuss the documents with the committee in a closed-door meeting, but still was unwilling to provide the committee members copies of the documents in advance.

“He will have to bring with him all the documents related to the USB key and he will have to answer all our questions,” said PQ transport critic Martine Ouellet.

Premier Philippe Couillard said UPAC is doing its job.
