[2] Walker owned a number of South Dakota theatres along the Northern Pacific Railway route, which terminated at Winnipeg.

[5] The building's auditorium, lobby and lounges were decorated with Italian marble, plasterwork, gilt trim, velvet carpets, silk tapestries, murals and crystal chandeliers.

[5] The interior features vaulted ceilings, reaching a maximum of 60 feet (18 m) in height, huge sidewall arches, 2 curving balconies, a fly tower and broad wings.

[3][5] The top balcony was built for inexpensive ticket holders: it was steeply raked and furnished with wooden pew-like benches.

[3][6] Fireproofing features included a steel cage system, many structural members being encased in concrete or terracotta, concrete floors (covered with fire-resistant wool carpet), fire-retarding metal doors between spaces, brick and terracotta firewalls, and slate-covered metal stairways.

It was also used during this period for political rallies, including the labour and women's suffrage movements such as debates and a mock parliament that Nellie McClung took part in.

[3] In 1933, the theatre closed on account of the Great Depression, and in 1936 it was seized by the City of Winnipeg due to unpaid taxes.

[9] In Spring 2016, True North exercised its option to purchase the building from the Walker Theatre Performing Arts Group.
