Most of the COR, including the original PECR route, has been converted to rail-trail use. After its abandonment the line has increasingly been turned to local authorities for maintenance. The route of the original PECR was purchased by Prince Edward County in 1997 and is now known as the Millennium Trail, running for 49 km out of Picton and ending just outside Trenton.
The 17 km section between the 401 at Trenton and Glen Ross had been re-used for roadways and other uses, as well as being in a built-up area. The unused sections in this area only started conversion to trail use in the 2000s, and several of these sections opened in 2011. Just north of Trenton this is known as the Jack Lange Memorial Trail, and from there, from just south of Glen Miller to Glen Ross, it becomes the Lower Trent Trail.
The largest section of the trail network is the 156 km long four-season Hastings Heritage Trail, stretching from Glen Ross all the way to Lake St. Peter Provincial Park outside Maynooth. This is the official end of the line, where it hits the border between Hastings County and South Algonquin. The trail remains in good repair, signed and used, north of this border to its current ending point near McKenzie Lake, at the intersection of McKenzie Lake Road and McKenzie Lake North, marked on many maps as the village of Gunters.
The short remaining section from Gunters to Wallace is used for a variety of purposes, including section of McKenzie Lake Road, Hydro One lines providing local service, and in some areas simply abandoned and heavily overgrown. The ultimate terminus can be seen a few meters to the west of McKenzie Lake Road at the ghost town of Wallace.
Congratulations to Skyee for getting her slealthy steed out and peddling The COR and earning all the FTF!
