If you look at this photo, the car is being loaded onto the back of the flatbed towtruck; it is not tarped at this point. I believe the police tarped it for transport as is usually the case.
As for not finding the vehicle earlier, I am not surprised. I'm in the Canadian Army and travelled from Base Borden every Friday night to Base Petawawa and back again every Sunday evening for a year through Algonquin Park.
Huge swathes of Algonquin are not deciduous trees and therefore the leaves are not falling, huge swathes of the park where cellphones don't work. And, in the winter, the park gets a tonne of snow. It would take me approx. 50-60 minutes to drive from West gate to east Gate (and vice versa) in summer/spring but me and my jeep in 4 wheel drive would often take upwards of 3.5 to 4 hours in the winter depending on how many hours since a plow had been through. Travel between those two gates is on the "main" road and many of the side roads into the camp sites are not plowed out (or plowed out all the way into the interior) in winter nor used by snowshoers or cross country skiiers. Rocking in the summer and spring months, Algonquin is very desolate in the winter.
I once towed an old lady and her small little Kia out of a ditch about 15 kms inside the East Gate during a severe snowstorm, made sure she was OK and followed her back to her home in Whitney to make sure she was OK. I've no idea what she was thinking trying to attempt that park, in that car during that storm.
I've done the 3+ hour winter drive through there many times and not seen another vehicle or a plow on the road. The husband and I had a system whereby I'd either call him from the Hunstville Timmies (about 15 minutes from the West gate) or Whitney (maybe 5 minutes from the East gate) before entering the park in winter and then would call again once I reached the town at the other end. The agreement was that if 4 hours had passed without the "I'm through the park" call from me, then he would make contact with the OPP.
I'm in Victoria BC this week on business, but will find some pics that I have of the park taken during some of my trips through in the winter when I get home. There are some doozies of the road.
