Ministry of Highways
MOH
Saskatchewan • Canada
The Saskatchewan Ministry of Highways manages over 26,000 kilometers of provincial highways in a province known as Canada's breadbasket, generating some of the highest agricultural freight volumes in the country. Key freight corridors include the Trans-Canada Highway (Highway 1), Highway 16 (the Yellowhead Highway), Highway 39, and Highway 11. Saskatchewan is the world's largest exporter of potash and one of the top producers of wheat, canola, and lentils, making heavy freight permitting and road maintenance critical priorities. The ministry administers oversize and overweight vehicle permits essential for grain augers, combine harvesters, and potash mining equipment, and provides the Saskatchewan Highway Hotline for road conditions.

Notable Rules
Saskatchewan permits B-train combinations up to 27.5 m on designated corridors. Grain transport is the dominant commercial freight movement — Saskatchewan produces more wheat and canola than any other province. Potash mining in the south-central region generates significant heavy haul. SGI (Saskatchewan Government Insurance) administers commercial vehicle permits.
