4414 is tracking at Leslie so the truck was probably used because access between Leslie an Hillcrest is severed with the work on the Bathurst Station loop.
When I got the photo and was told the directions I was really puzzled too. I made sure to verify that the building on the left (just to the right of the Canada Post truck) seemed to be in the right place. Note the front of the car was facing away from the truck cab.
La Pocatière is served by CN so given the route it probably was pulled off in Brampton. Maybe there are some challenges with the height that made them go that way.
