Canada Coach Lines bought 7 PD-4104s (Parlor series bus, Diesel engine, 41 passenger, model #04) in 1958 and 1959.
Some of the dates for these photos are unknown, and the locations are often just a guess. If you know either date or location, email me!
A drawing of a PD-4104 graces the cover of this CCL Bus Schedule, dated April 27, 1962.
