[1] To accomplish this, MTS needed to expand its Corydon Ave. long-distance switching centre by adding four additional storeys to the building.

[1] Initial communities to be set up with the new long-distance hardware included Boissevain, Deloraine, Dauphin, Kenton, Melita, Waskada, Lyleton, Tilston, Portage la Prairie, Pierson.

[3] Also in the late 1950s, MTS located one of its administrative offices on Empress St. near the newly opened Polo Park Shopping Centre complex.

In 1981, it partnered with Infomart (then owned by the Torstar and Southam newspaper chains) to create the Grassroots service, providing information relevant to farmers on the Canadian prairies.

They opened MTS Phone Centre stores in shopping malls to sell residential and business phones and services, and in 1984 opened two MTS Business Centre locations (Commodity Exchange Tower lobby and Empress St. office) to provide sales of business-level equipment.

[14] In 1996, the Provincial government of Premier Gary Filmon decided to sell the Manitoba Telephone System to private shareholders.

The decision to privatize was seen as controversial, as it marked a significant departure from the Progressive Conservatives' earlier position that MTS should remain provincially owned.

[15] In January 1999, MTS partnered with Bell Canada to form Intrigna, a Competitive Local Exchange Carrier (CLEC) which was created to expand telecommunications options for the business market in Alberta and British Columbia.

[16] In August 1999, MTS completed work on a new trunked (digital) radio system known as FleetNet 800, technology licensed from neighbouring SaskTel.

[16] In the Fall of 1999, MTS began to offer DSL high-speed Internet service in Winnipeg and Brandon, which later expanded to other areas of the province.

[16] The CRTC met with the various telecommunications providers in Canada and required of them to implement a Service Improvement Plan (SIP).

[28] On May 2, 2016, BCE Inc. announced that it would acquire MTS in a $3.9 billion all-stock deal, paying $40 per-share and assuming $800 million in debt.

As a condition of the sale, Bell agreed to divest one-third of MTS Mobility's wireless subscribers and MTS retail locations to Telus; the divestment aimed to give the three national carriers (Bell, Rogers, and Telus) a roughly equal market share in Manitoba.

This aspect of the deal will maintain the presence of four competing wireless providers in Manitoba, with the fourth being a new entrant to the market.

[34][35] The acquisition closed on March 17, 2017; at this time, Dan McKeen (who led the integration of Bell Aliant into the company's national operations) was installed as the new head of the division, replacing the outgoing Jay Forbes.

[36] Bell stated that it intended to maintain MTS's existing wireless pricing structure for at least a year after the closure of the acquisition.

[42] MTS Classic TV was the company's legacy digital television service; it was discontinued in 2015 due to its incompatibility with Alert Ready.

[45] Bell MTS also offers cable television service in Carman, Holland, Manitou, Miami, Morris, Notre Dame de Lourdes, Plum Coulee, St. Claude, St. Jean Baptiste, Treherne, Altona, Morden, and Winkler.
