New court documents filed by the RCMP allege suspended senator Pamela Wallin fraudulently billed the Senate for more than $25,000 in expenses she incurred on trips to Toronto and Guelph “to pursue her personal and business interests.”

The Mounties allege Wallin submitted 21 expense claims to the Senate for travel to events related to her involvement with BMO Nesbitt Burns, Bell Media, which owns CTV News, and the University of Guelph between 2009 and 2012.

None of the allegations has been proven in court and no charges have been laid.

The latest allegations are outlined in documents seeking a court order to get more documentation from the mentioned companies and university. Wallin sat on the advisory board for BMO Nesbitt Burns, served as an independent director for what was then known as CTV Globemedia, and served as chancellor of the University of Guelph.

In the court documents, the investigating RCMP officer alleges that a number of Wallin’s trips to Toronto and Guelph for board-related or personal business coincide with some of her 150 Senate travel expense claims that are under investigation.

The RCMP alleges Wallin said she was on senate business while she appeared on the CTV News election night special on May 2, 2011.

CTV News records show Wallin was paid $165 for a car service in relation to the network’s election special.

While acting as chancellor at the University of Guelph, Wallin also allegedly claimed expenses for Senate work as she attended convocations at the school.

“I believe that by submitting these 21 travel expense claims to the Senate Finance and Procurement Directorate for reimbursement under the representation that the activities she undertook were ‘Senate Business,’ Senator Wallin committed a fraud and a breach of trust by a public officer,” Cpl. Rudy Exantus wrote.

In previously released court documents, the RCMP alleged that Wallin misrepresented 25 travel expense claims as “Senate business,” when in fact she was attending meetings or dinners related to her position as a board member of Porter Airlines and Gluskin Sheff & Associates Inc.

None of those allegations has been proven in court either.

Wallin, along with fellow former Tories Patrick Brazeau and Mike Duffy, was suspended from the Senate in November 2013 over inappropriate expense claims. Liberal Mac Harb resigned from the Senate in August 2013 after repaying ineligible housing and travel expenses.

Duffy faces 31 charges, including multiple counts of fraud and breach of trust. His trial will begin on April 7. Brazeau and Harb have also been charged with defrauding the Senate by making false or misleading expense claims.
