Only a short portion of the OA&PS remains in use, between Arnprior and a diamond junction with the CN mainlines just east of Ottawa. The route used to carry the lines into downtown Ottawa, but all rail lines in the area were removed in the 1960s as part of an urban beautification project, and moved south to the new Ottawa Train Station. The majority of the line's original Ottawa-area route is now part of Ontario Highway 417, also known as The Queensway, although a short section forms part of the Watts Creek Pathway on the western end of town.
