What's now called the Union Station riding was created in 2008 from parts of the Point Douglas and Fort Rouge ridings and the former Wellington and Minto ridings. It was known as the Logan riding until 2018, when its boundaries were redrawn so it no longer included its namesake, Logan Avenue.

Union Station's total population is 23,065, according to Elections Manitoba's riding profile, based on the 2021 census information collected in the province.

The downtown Winnipeg riding's boundaries are Notre Dame Avenue, Portage Avenue, Westbrook Street, Pioneer Avenue and the CN rail line in the north. To the east, it continues along the Red River, then runs west along the Assiniboine River, Osborne Street and Broadway. Its western boundary is Maryland Street.

The riding covers most of downtown, including the University of Winnipeg, the Canadian Museum for Human Rights and the Manitoba Legislature.

The riding's median age is 34.8, Elections Manitoba's 2023 riding profile says, based on information from the 2021 census. The median household income is $42,400.

The Union Station riding (and its predecessor, the Logan riding) has only ever voted for the NDP. In 2011, Flor Marcelino was elected with nearly 3,000 of just over 5,100 votes cast, or nearly 60 per cent of the vote. Marcelino was re-elected in 2016 with a little over 2,000 of more than 5,200 — or less than 40 per cent of votes cast. She was succeeded by rookie Uzoma Asagwara in 2019, who brought in nearly 3,000 of almost 5,600 votes (or 52 per cent of ballots cast).

The nominated candidates for the 2023 election, as of Sept. 6, are:

Candidates become official when they meet criteria set out in the province's Elections Act, including providing a statement of disclosure, after the election has been called. In Union Station, all candidates are official.
