The Ontario Provincial Police say they received a series of calls just after 5 a.m. on Sunday, about an eastbound Escalade on the westbound lanes of Highway 407, near Goreway Drive in Brampton.
Police say the vehicle was stopped without incident.
The 35-year-old driver was subsequently charged with dangerous driving, impaired driving, driving under suspension, failing to provide a breath sample, and driving on a prohibited highway on a G1 licence.
The accused is being held for a bail hearing, police say.
Under Ontario’s graduated licensing system, drivers must pass through a series of tests before earning their full and permanent driver’s licence.
The initial licence is called the G1, under which drivers must have a zero blood-alcohol level and must stay off 400-series highways. These licence holders must also operate the vehicle alongside a driver who has been licensed for at least four years.
Drivers must then pass a test to be granted a G2 licence, which allows them to drive alone but they cannot have a blood alcohol level above zero. A further test leads to a full G licence, at which point the legal limit rises to 0.08.
However, recent legislation mandates all drivers below the age of 21, regardless of licence level, to maintain a blood alcohol level of zero.
