The government of Saskatchewan announced this week that they would no longer allow vehicles with Alberta plates on provincial highway construction sites.

David Marit, Minister responsible for SaskBuilds, attributed the decision to "many" Saskatchewan contractors telling him vehicles with Saskatchewan plates aren't welcome on Alberta construction sites.

"Saskatchewan companies have felt compelled to register their vehicles in Alberta in order to do business in that province," Marit said. "Furthermore contractors from Saskatchewan, British Columbia and Manitoba pay provincial sales tax on the value of their vehicles when they register them."

Alberta's Minister of Economic Development and Trade, Deron Bilous, has threatened to take the Saskatchewan government to court if they didn't go back on their decision.

Marit says he values work done by Albertan companies, but that the policy "levels the playing field between Alberta contractors and contractors from Saskatchewan, British Columbia, Manitoba, Ontario and other provinces."
