Need help identifying locomotive

What model of switch locomotive is this? I saw it last year in CN’s Sarcee Yard in Calgary. Saw it again last June at Sarcee Yard, the CANAC lettering had been painted over and a chain was on to prevent entry into the engine compartments. A day or two later it was moved to a grain elevator spur north of Calgary.

From the Alberta Centennial Rail Museum website:

"This is an ex-Canadian National S-13u locomotive number 8704, donated to the museum on March 11, 2003, by Canac Inc., which is a locomotive and equipment leasing company based in Montreal.

The locomotive was originally built for the CNR in 1959 by Montreal Locomotive Works as model S-13. The CNR purchased 49 units in the same year and numbered them 8500-8522 and 8600-8625. The latter units were equipped with MU control for operation in hump yard service, and were heavier, had dual sealed-beam headlights, different gearing and traction motors. The locomotives were delivered in the black and yellow livery with the maple leaf monogram under the cab window."

In the early 1980’s, a fair number of the S13’s were assigned to Toronto, and some were used in passenger switching out of Spadina for Toronto Union Station. Spadina was an Alco heaven at the time, with S13’s in switching and FPA/FPB’s and LRC’s in passenger service.
