Two people have been seriously injured in an overnight snowmobile collision near Renfrew.

Shortly after midnight Sunday, Ontario Provincial Police were called to a trail near Goshen Road in the township of McNab/Braeside.

Four snowmobiles had been traveling together when the collision happened, said the OPP in a release.

The male driver of one snowmobile was taken to a local hospital then airlifted to a second hospital with "critical" injuries, police said.

A female passenger on a second snowmobile was also taken to hospital with serious injuries, said police.

Alcohol has not been ruled out as a factor in the crash, the OPP said.

First of 2 snowmobile incidents Sunday

The Renfrew-area crash was the first of two incidents involving snowmobilers in eastern Ontario Sunday.

Shortly after 2:30 p.m., Ottawa Fire Services received a 911 call that a snowmobiler had gone into the Ottawa River near Bayview Drive in the community of Constance Bay.

The caller later updated that the snowmobile driver was able to get himself out of the water on his own.
