MONTREAL — A shortage of truck drivers curtailed Resolute Forest Products’ ability to ship wood chips to its mills last December, said the company’s former president and CEO, Richard Garneau.

CTV News reports that Garneau discussed the transport problem during a conference call on Thursday, prior to his retirement from the pulp and paper company.

Garneau said Resolute slowed production in December “after a shortage of truck drivers working as subcontractors and harsh winter conditions resulted in a lack of wood chips at its Quebec pulp and paper mills.”

He told analysts Resolute is not the only company facing this problem.

Resolute is trying to adapt by using larger trailers to haul chips and shipping more volume by rail.
