facility was renamed the Hummingbird Centre in recognition of a major gift from a Canadian software company, Hummingbird Communications Ltd. The $5-million donation allowed the Centre to undertake a number of capital improvements and repairs, including the installation of an elevator and an acoustic reinforcement system for the auditorium. In October 2006, OpenText acquired Hummingbird and declined to renew its contract with the centre. In September 2007, Sony bought the naming rights to the Centre for $10-million, and a ten-year partnership was born. When the Ballet and Opera moved to the Four Seasons Centre in 2006, it left a hole in the theatre's schedule. At this point, programming shifted to a multicultural schedule by include more content appealing to Toronto's many ethnic diasporas. Notable performances that reflect this mandate include The Last Empress (a Korean historical musical), the Virsky Ukrainian Dance Company, South Africa's Soweto Gospel Choir, The Shaolin Warriors, Ricky Cheng, David Rudder & Friends and Club Tropicana. In 2006, the performing arts venue received approval from the City of Toronto for the development of a high-rise condominium building beside the Centre.

On 21 January 2019, the City of Toronto announced a C$30.75 million 15-year partnership with Meridian Credit Union, re-branding the Sony Centre into Meridian Hall, and the Toronto Centre for the Arts into the Meridian Arts Centre. The arts venues formally adopted their new names on September 15, 2019. Architecture Designed by Peter Dickinson, the performing arts venue is a distinctive building and an example of a mid-twentieth century modern performing arts venue. It is four storeys high and is broken up into three main forms: the entrance block, auditorium and fly tower. The central form of the building is highly symmetrical with an open floor plan. Structurally, the performing arts venue is not overcomplicated and uses steel trusses and concrete to hold the majority of the building together. In addition to the structure, the performing arts venue's auditorium houses a very sophisticated acoustic system, which gives
