Note that the Parkway is merely a controlled-access portion of the three numbered highways, two of which (Highway 7 and Highway 8) continue for some distance beyond the freeway referred to as the Conestoga Parkway. Thus, the freeway has the distinction of being one of the few Ontario-maintained freeways not numbered according to the 400-Series Highway network, even though it is busier and wider than many rural 400-series highways, because the freeway upgrade has joined together only parts of existing routes. In comparison, the 400-series highways are intended to be full freeways for their entire length.
