It's been a deadly Victoria Day weekend on Ontario highways and it's not even over yet.

Five collisions since Friday have left six people dead, outpacing the number of highway fatalities during the 2010 holiday weekend by two.

This despite public comments from the OPP to drive safely and exercise caution on a weekend regarded as the unofficial start to summer.

"We have seen collisions throughout the long weekend and unfortunately a lot of them are preventable," Const. Dave Woodward told CP24 Sunday. "The biggest advice is just to stay focused on your driving at all times and avoid the distractions whether it be phones, texting or even other distractions inside the vehicle."

The rash of highway accidents started Friday afternoon when a 54 year-old man died on Highway 10 near Orangeville after a tractor trailer overturned onto his vehicle. In a separate incident Friday a vehicle collided with a train in Rainy River, killing one.

On Saturday a 50 and 53 year-old-man died as a result of a head-on-collision north of Campbellford and a 24-year old man died after being struck by a transport truck while crossing Highway 17 near Ottawa.

On Monday afternoon a woman was killed when her vehicle collided with a passenger train in Sundridge, south of North Bay.

The accidents weren't restricted to outside of the Greater Toronto Area either.

On Saturday afternoon eight people were sent to hospital with non-life threatening injuries following a three-vehicle accident on Highway 400 near the Cookstown Outlet Mall in Newmarket. That accident tied up traffic for several hours.

Woodward suggested a high number of vehicles on the road may have had something to do with all the accidents.

"This is a long weekend and people have a tendency to get away and that means you get heavier traffic," he said.
