This prominent building was constructed for William B. Poulton, a painter and a Mason, primarily for use by the Masonic Orient Lodge. The block was designed by Kennedy, Gaviller & Holland, Architects, in Gothic Revival style. Early occupants of the ground-floor shops included a druggist and a bank. The third floor, marked by Moorish window arches, served as 'Orient Hall' until 1912. From 1888 to 1910, the Toronto Public Library's 'Eastern Branch', its first branch east of the Don River, was located in rooms at the back of the building.
