That's a 19.6-per-cent increase over last year's numbers, when 225 fatalities occurred on provincial roads.
Additionally, one person was killed over the weekend in an off-road vehicle incident.
The OPP has wrapped up Operation Impact, a national initiative aimed to improve road safety, save lives and reduce serious injuries through increased awareness and compliance with traffic safety laws.
Over the weekend, the OPP targeted speeding, aggressive driving, distracted driving and occupant restraint during the campaign — officers laid more than 11,700 charges relating to these four main factors in road fatalities.
The OPP said it continues to work with its police partners across Canada in an effort to increase public compliance with safe driving measures and ultimately, to save lives while making Canada’s highways the safest in the world.
