Scarborough—Rouge River (federal electoral district)

Scarborough—Rouge River was a federal electoral district in Ontario, Canada, that has been represented in the House of Commons of Canada between 1988 and 2015. However, as of the Fall 2015 federal election, part of this riding has been combined with the south-western part of the old riding Pickering—Scarborough East.

The riding covered the northeast part of the Scarborough part of Toronto. It stretched from Highway 401 in the south to Steeles Avenue in the north. In the east it ended at the border with Pickering and in the west at Midland north of Finch and Brimley south of Finch.

Scarborough—Rouge River has the highest percentage of visible minorities in all electoral districts (89.7%) and the lowest percentage of White Caucasians (10.1%). Chinese make up 30.8%, South Asian 32.8% (all South Asian countries), Black 10.7%, White 8.7% Tamil is the mother tongue for 13.2% of the population, which is the highest such percentage for that language among all ridings; likewise for Tamil as a home language (10.5%). 13.6% of the population is Hindu, the 2nd highest in Canada after Brampton East.

In the 2011 federal election, the NDP were elected for the first time. The riding was abolished before the 2015 election. The western portion, along with most of its population, became part of Scarborough North, while the eastern portion became Scarborough—Rouge Park.
