A 23-year-old Markham man, suspected of drug impairment, faces numerous charges following a serious collision between a sport utility vehicle (SUV) and a tractor-trailer that closed Hwy. 7 for nearly five hours.

The collision took place shortly after 2:30 a.m. on Oct. 19 near Commerce Valley Drive at Markham. Both vehicles were left with significant damage. As well, the tractor-trailer was leaking fuel onto the roadway.

The SUV driver was charged with impaired driving by drug, dangerous operation of a motor vehicle, driving while under suspension and novice driver – no accompany driver and novice driver – at an unlawful hour.

“We are concerned that the recent legalization of recreational cannabis will result in more incidents of impaired driving,” said police chief Eric Jolliffe, in a news release. “We are urging anyone that has used cannabis, any other type of drug or consumed alcohol to not get behind the wheel. Our citizens can expect to see our officers on patrol and conducting R.I.D.E. spot checks throughout the region in an effort to stop anyone who has made the choice to drive while impaired.”

An impaired-related charge in any vehicle will result in an immediate 90-day driver’s license suspension, an ignition interlock device being installed on all vehicles you operate for at least six months, as well as a mandatory education or treatment program. These consequences are separate from any court outcomes.
