For the M2 exit. It will be through an industrial, a commercial, and a residential area, as well as one entrance and exit of a nearby highway. A long sweeper, and a safe spot for an "emergency stop" will also be included. All will be fairly close to the testing centre, although the exact route may vary among several.
I would kind of expect the highway portion to between 27 and 40 (communications Rd). But I've never done a test there, so I could be wrong.
14 where it hit Communications Rd looks like a good sweeper from the map.
Richmond St, Park Ave, Oriole Pkwy and through parts of Wilsonwood would be my guess for one of the possible routes. There should also be a fairly wide paved shoulder area, where the stop would be, possibly on a bridge.
