OpenStreetMap
Traced some more gpx files in Brantford, something isnt right with my GPS though, some streets are too close together (Albion and Pearl). Also, traced another route between Brantford and Ancaster (Jerseyville Road) quite a fun drive in the winding roads.
Fied up the roads in Ancaster I was missing, still not all of the subdivisions are in though, seems like a new one pops up all the time. Drove out to Sulphur Springs and Mineral Springs Road, ignored all the compaining my car did, again fun with the winding dirt roads. These ones could have been traced off the Aerial but due to tree density, connecting the dots would have taken quite the imagination. Just easier with the gpx.

I often find that shortly after turning on my GPS, the accuracy can be wildly out. I sometimes find some wide random variations, where the trace just goes out. Taking the trace 2 or 3 times at least 6 hours apart (to allow the satellites to move) and comparing them, could help allow you to verify if the first trace was correct.

yeah I have noticed that too, when you first turn on the gps the first few minutes the data is not great, I now dont use the first few minutes of data,
