I don't personally have a dash cam, but here are a couple of YouTube videos from the Moncton area (they both make our weather here look pretty dreary).
The first one starts on Main Street in Moncton, then follows Rte 15 northbound, then the TCH eastbound to the NS border and then on to Amherst NS, a distance of about 60-70 km.

The second video starts just south of Shediac on Rte 15 southbound, then the TCH westbound, ending about halfway around the periphery of Moncton. This video shows both of the infamous level railway crossings on the Trans Canada Highway.
