RCMP in Manitoba are continuing to investigate after a semi pulled over on the weekend was allegedly found to be carrying over half a tonne of illegal cannabis.

The Manitoba RCMP says in a release that RCMP Traffic Services stopped the semi on Highway 1 in the RM of Reynolds, MB for a Level 3 inspection just after 10:30 Saturday morning.

"Inconsistencies in the driver's paperwork led police to a load inspection under the provisions of the Excise Act, 2001," the RCMP says.

It was during that inspection that officers discovered approximately 1,250 lbs of unstamped dried cannabis and hash onboard the semi-trailer.

Police say that the 41-year-old male driver, from Surrey, BC, was arrested and will be facing multiple charges under the Cannabis Act, the Excise Act, 2001, and the Liquor, Gaming, and Cannabis Control Act.
