The OPP say that high-risk driving is a continuing and dangerous problem.
In just one day of enforcement this week, they stopped five people for stunt driving on Highways 401 and 403 in the GTA.
The drivers were going between 157 and 188 km an hour, and they range in age from 21 to 36.
"Unbelievably dangerous," says OPP Sgt Kerry Schmidt. "People lose their lives because of (those speeds)."
All five men had their licenses suspended and cars impounded for a week.
