Episode 6 spoiler-ish stuff inside.
I recognize most of the background scenery, and I can tell you that most of the scenes through B.C. were shown in order.
I don't know the Kootenay backcountry at all, but I know there are no such places as "Wolf Mountain" and "Bear Pass". sketchy_waffles on Reddit confirms that it's Reco Mountain, between New Denver and Kaslo.
Granville Street bridge leaving (or heading into?) downtown Vancouver.
Trans-Canada Highway (Highway 1) through Coquitlam towards the Port Mann bridge.
Going through Chilliwack.
Lost opportunity for a "we're beyond Hope" joke here.
sign trailer on the right: "Watch Highway Thru Hell September 4th on Discovery Channel".
More "Highway Thru Hell"/Jamie Davis Motor Truck merchandise in the background.
Clarkson's truck has no plates at all. I couldn't even find a B.C. temporary permit anywhere on it, even though it's nothing more than a sheet of paper you tape to your window. James' truck has an Alberta plate with a Fleet Prorated registration, so it's owned by a company. But I don't think it's a rental, as Alberta rental plates are in a A-12345 format.
I live in Kamloops. This shot is likely as close to "local" that TG will ever get for me. Leaving Hope, they take the Crowsnest Pass (Highway 3). I've never travelled it, so the highway scenes from hereon in (such as the lede photo) don't look familiar to me.
Obligatory. Love it or hate it, Crappy Tire is as uniquely Canadian as Tim Horton's.
Canadian Tire-branded hats...
And then they markered-out the "Tire" so as to not advertise, I guess. Kinda pointless right after the shot outside the store. Besides, why not just buy non-branded hats?
The door mat gives away that this is a Lordco, not a Cambodian Tire. It's this one in Oliver, B.C. The C.T. is likely the Oliver one, also.
Finally, the attractive small town in which James wants to stop for a Cappuccino is Keremeos, 45 minutes west of Oliver. It's the only scene that I could tell was shown out-of-order. I presume they did so in order to show the snow progressively getting thicker as they travelled towards Hammond.
I was pleasantly surprised to learn that the amount of "movie magic" was much less than I imagined it to be.
