Winter weather conditions have made area highways treacherous.
A man was killed on Highway 11/17 near Shabaqua just after 3 p.m. when a pickup truck rolled over just one kilometre west of the turn off to Finmark Road, and the highway was closed to one lane as the investigation proceeded.
The OPP was not able to provide further details about the incident.
Meanwhile, a two-vehicle collision on Highway 61 between Riverdale Road and Mount Forest Boulevard sent a male to Thunder Bay Regional Health Sciences Centre in critical condition.
The incident heavily backed up traffic on the highway during the middle of the afternoon, as southbound traffic was lined up from Chippewa Road all the way to the Neebing Avenue and Princess Avenue intersection.
The highway was temporarily closed, with southbound traffic being rerouted down Chippewa Road.
There were three other vehicles visible in the ditch along Highway 61 between the scene of the collision and Broadway Avenue in isolated incidents.
