Orillia OPP has arrested and charged three people after impaired driving led to collisions.
The three drivers were each involved in collisions, two of which caused part of Highway 11 to be closed for brief periods of time.
A 55-year-old woman from Markham, a 30-year-old man from Barrie, and a 54-year-old from Toronto will each make their appearances in court over the coming weeks.
One driver had suffered minor injuries and was treated at a local hospital before being released.
