The development of the West End as a residential expansion came during one of Winnipeg's largest periods of growth between 1890-1895 and 1900-1912. The area was originally a part of the Parish of St. James until the boundary of the City of Winnipeg was extended to St. James Street from Maryland Street (formerly Boundary Road) in 1882. Development of the area as a working and middle class residential area began in the late 19th century and continued through the 1920s until the area was completely built up. The area developed rapidly due to its proximity to Downtown Winnipeg, and, unlike Winnipeg's North End, the mainline of the Canadian Pacific Railway did not impose a physical barrier between the West End and Downtown. The area was also well served by the city's street railway system with lines on Portage Avenue, Sargent Avenue, Sherbrook Street, and Arlington Street. The industrial area located adjacent to the railway spur between Wall and Erin Streets provided employment for many West End residents.
