Ontario Provincial Police Constable Graham Williamson said the driver lost control of the truck, which was carrying 235 pigs, on the ramp leading from southbound Highway 427 to the eastbound Gardiner Expressway and the vehicle overturned, the Canadian Broadcasting Corp. reported Monday.
Police said the junction would remain closed until the 60 escaped pigs are herded off the roadway. Authorities from the Canada Food Inspection Agency were called to the scene to examine the animals.
The truck driver, who was not injured, was charged with careless driving, police said.
