Manitoba Theatre Centre, 174 Market Avenue - Manitoba Theatre Centre National Historic Site of Canada is located in downtown Winnipeg, Manitoba, within Exchange District National Historic Site of Canada. The site consists of a Brutalist structure, which features exposed reinforced concrete and substantial massing. It was built between 1969 and 1970 as part of an urban renewal project to create a complex of modern public buildings in downtown Winnipeg. It was also constructed to house the Manitoba Theatre Centre’s regional theatre group, which was established in 1958. Official recognition refers to legal lots 2, 3 and 4.

Manitoba Theatre Centre was designated a national historic site of Canada in 2009 because: - it is an excellent expression of small-scale Brutalist architecture in Canada in its poured concrete forms, solid massing, interior layout and exposed structure; - it is an exceptional theatre building because it creates an intimate atmosphere in the auditorium and foyer for its patrons, and encourages, through its architecture, a stronger relationship between audience and actor by allowing theatregoers to observe stage activity behind the curtain and sense the players' anticipation of the performance; - it is associated with the Manitoba Theatre Centre group, which was judged to be a model regional theatre by the Canada Council for the Arts, and played an important role in popularizing the regional theatre movement in Canada.

The opening of the Manitoba Theatre Centre (MTC) building in November 1970 concluded a long tradition of theatre building in Winnipeg. As part of a cultural renaissance of the city’s arts facilities in the 1960s, the MTC building housed Canada’s first professional regional theatre group. At a time when large modern theatres and concert halls were opening up across the country, the MTC was designed as an intimate space that permitted a close relationship between audience and actor. In addition, the Manitoba Theatre Centre was the country’s first large regional theatre group with educational programming and shows touring throughout rural Manitoba. The newly founded Canada Council funded the theatre and promoted it as the exemplary model of how to create a successful regional theatre.

The MTC is also an excellent expression of small-scale Brutalist architecture in Canada. The buildings sculptural form of exposed reinforced concrete, undressed formwork and solid massing are key features of the style. The east and north façades of the building feature sculptural double-height angled windows, designed to allow natural light into the public foyer. In addition, the north side of the building is punctuated by four semi-circular concrete projections on the ground floor. There is an overall informality and asymmetry to the building that is characteristic of small-scale Brutalism.

Equally important is the MTC’s interior space. At a time when Brutalist architecture was being well received publicly as modern design, the MTC building introduced a new concept of intimate Brutalist architecture. Rather than a formal event space, the architects and theatre director worked together to create a space that bridged the separation between the actors’ and the audience. The theatre’s asymmetrical seating arrangement, flexible stage design including a proscenium and "thrust stage," and foyer, are good representative examples of this concept. The scenery preparation room behind the stage is also open to viewing by theatregoers through a window, allowing a glimpse behind the stage and furthering the intimate theatre experience.
