The Countess of Dufferin was the first steam locomotive to operate in the Canadian prairie provinces and is named after Hariot Hamilton-Temple-Blackwood, Countess of Dufferin (later Marchioness of Dufferin and Ava), the wife of the Earl of Dufferin, a Governor General of Canada. The locomotive was built by the Baldwin Locomotive Works (builder's plate No. 2660) and delivered to Northern Pacific Railway as No. 21 in 1872. It was used in Minnesota and the Dakota Territory until 1877 when it was sold for $9,700 to Joseph Whitehead, a contractor for Canadian Pacific Railway. The locomotive, along with six flatcars and a caboose, was loaded onto barges at Fisher's Landing, Minnesota, and propelled by the SS Selkirk, they were shipped down the Red River to St. Boniface, now an electoral district
