Rossmere is bordered on the southeast by Radisson, to the south by Elmwood and Concordia, to the north & west by Kildonan-River East.

Although Rossmere's first MLA was New Democratic Party premier Edward Schreyer, it was historically a swing seat between the NDP and the Progressive Conservatives.

Schroeder was a senior cabinet minister in the government of Howard Pawley, but was defeated in the 1988 election that swept the NDP from office.

Progressive Conservative Harold Neufeld held the seat from 1988 to 1993, while future MP and federal cabinet minister Vic Toews was the MLA from 1995 to 1999.

Schellenberg was succeeded by fellow NDP member Erna Braun, who won the seat in 2007 provincial election with 60% of the vote.
