Glenburn Dairy, Burnaby and maybe Vancouver
According to this article, which includes a photo of the former plant, the dairy operated form the 1930's to the 1950's at the corner of Hastings Street and Boundary Road and was run by Charlie Haslam. A later photo of the plant can be found here. Hill's book lists the dairy as operating in Vancouver, and since the cities are directly adjacent to each other there was likely some crossover.
