Mission, formerly known as Rouleauville before being annexed into Calgary, was incorporated in 1899 after having been settled by Roman Catholic Oblate missionary Father Constantine Scollen. Rouleauville was named after Charles and Édouard Rouleau. Charles Rouleau is best known for his legal career, having been a Justice of the Supreme Court of the Northwest Territories prior to the creation of the province of Alberta. It was expanded in 1883 by Father Albert Lacombe, having seen the need to secure a Mission district to ensure a strong francophone community.
Despite this, Rouleauville gradually lost its francophone identity and in 1907, Rouleauville was annexed by The City of Calgary. Until recently, Mission's French background had disappeared, but has made a resurgence with the original French street names being reintroduced on street signs and stop signs.
Cliff Bungalow was developed in the 1870s on Canadian Pacific Rail land, though it is less storied than Mission. It was slowly annexed by the City of Calgary between 1906 and 1912. It was originally a low-density neighbourhood for CPR employees due to its proximity to the offices and railyard of the company. In 1935, long after its annexation into the city, Cliff Bungalow began densifying, with medium-density apartments being permitted. In 1970, Cliff Bungalow was officially given its name, having only been informally referred to as such by Calgarians.
