Went for a ride today (I'm on holidays).
Checked out the Bruce County Rail Trail which is now open for bikes with OFTR membership.
Here is the gpx route to follow the trail: https://www.wikiloc.com/trail-bike-trails/bruce-county-rail-trail-27468180
Did about 170km from Clifford, On, up to Saugeen Shores, and over to the Bruce Nuclear plant and then back to Clifford.
It's a good trail. Some sections have small whoops; loose gravel near the lake, otherwise it is almost too smooth and flat.
