This weekend I have been out mapping a number of recently built bike trails in Toronto, Ontario using a GPS device. These were funded through a government infrastructure stimulus program. These were built along hydro corridors (high voltage power lines) and abandoned railways. There are also a few sections where a paved bike path runs along the side of a road, along Ellesmere Road and Morningside Avenue, with bike traffic signals at major intersections (like the existing bike path on Lake Shore Blvd near the Exhibition). Some sections of this trail system are still under construction, and are not finished yet.

and http://www.thestar.com/news/article/1049200--rush-to-build-bike-trails-resulted-in-a-major-disconnect?bn=1

At major road crossings bicycle traffic signals have been installed like the one shown in the Toronto Star article. These have not been turned on yet.
