A former Alberta premier who was found guilty of fraud, including the $20-million payout, will face a jury trial in 2019.

Brett Clark, 63, was convicted by a Calgary jury on Thursday and will spend up to 20 years in prison.

He was also sentenced to two years of probation.

A report by the provincial auditor’s office found Clark made a $20 million payout from the timber sale of Alberta’s largest timber company, Northern Forest.

Clark has denied wrongdoing.

The Alberta Forest Products Association has said the payout should not be used as a defence in the case.

In a statement, the association said it is disappointed that Clark’s conviction “does not represent the view of our members.”

It says Clark’s convictions “are in no way intended to deter our members from defending their rights and protecting the environment.”

“We have consistently opposed the misuse of timber sales to finance political campaigns and continue to work to protect our forests and watersheds from timber theft.”
