These lakeshore communities lie south of Kingston Road and the 401, just west of the Rouge River and the city limits. West Rouge is the area east of Port Union Road, and Centennial (named for its main north-south street) lies between Port Union Road and the Highland Creek parklands. In the 1800s Port Union was a major port and fishing village which grew in importance in 1856 when the Grand Trunk Railway built a station, though the port declined in significance. In the 1960s the area underwent a housing boom, and in the 1980s the development of the former Rouge Hills Golf and Country Club added housing in the Rouge Valley. In the 1990s, the redevelopment of the Port Union waterfront added high density townhouses.
Motorists access the Highway 401 via Port Union Road, which connects motorists to the Don Valley Parkways into downtown Toronto. Some commuters prefer to take Kingston Road west to Lakeshore Boulevard East. TTC buses along Lawrence Avenue, Lawson Road and Port Union Road connect to the Rouge Hill GO Train station which zips commuters to the downtown Union Station (in under 40 minutes), and the Yonge-University-Spadina subway line.
The community is served by 5 elementary schools, 1 Catholic elementary schools, 2 high schools, and 1 public library. Centennial College's Progress campus is just southeast of 401 & Markham Rd, and University of Toronto at Scarborough is at Ellesmere & Morningside.
Centennial Plaza (Port Union & Lawrence) is the local mall, however small, and there are a couple of small plazas around the neighbourhood. Shoppers also head north to The Villages of Abbey Lane (north of the 401), or west to Morningside Mall (Morningside & Lawrence)
The community has great access to Rouge Park, with a wetlands and a Lake Ontario Beach. There also is a campground north of the 401, accessed via Kingston Rd. To the west is Highland Creek with a deep ravine down to the Lake Ontario shoreline, with paved recreational pathways that head up the creek into the heart of Scarborough. The community has 3 baseball diamonds, 1 running track, and 3 tennis courts. The community is also home the very active West Rouge Soccer Club, and the West Rouge Canoe Club (which also hosts dragon boats).
The community's oldest homes are cottage dating back to the 1920s. Homes in this neighbourhood built over the 1940s and 50s are mostly cottages, bungalows, split-level homes, and 2-storey styles. Homes from the 1960s and 70s also include Tudor style 2-storey homes, and the Port Union Village close-to-the-waterfront development is mostly semi-detached and townhomes. Homes in Port Union are in the low to medium price ranges.
