The financial success of Toronto FC led MLSE to undertake a major renovation of BMO Field. Under a two phase process, the stadium's capacity was increased from 21,566 to 30,000 by May 2015, and a canopy roof covering most permanent seating areas was added and the pitch lengthened to accommodate a Canadian football field by May 2016. The renovations were originally budgeted to cost $120 million, but ended up at $150 million in total. In exchange for a $10 million contribution to the project by the City of Toronto, which owns the stadium, they receive rent from MLSE, while MLSE's management and naming rights agreements for the stadium, which were set to expire in 2027, were extended by 10 years. The province of Ontario also contributed $10 million to the financing. The City insisted that the renovations allow the Argonauts, who had to vacate their current home the Rogers Centre, to move in. The sale of the Argos in May 2015 to a new ownership group consisting of MLSE owners Bell and Tanenbaum was accompanied by an announcement that they had reached an agreement with MLSE to relocate to the stadium for the 2016 season. The Argos contributed $10 million to the conversion of the field to make it CFL compatible, which was matched by MLSE. MLSE financed the rest of the project, and was responsible for cost overruns. The renovated stadium can be temporarily expanded to a capacity of roughly 40,000 for big events. The Argos purchase agreement called for two Grey Cups to played at BMO Field, the first being the 104th Grey Cup in 2016, and the stadium was chosen to host rugby sevens at the 2015 Pan-Am games and the 2017 NHL Centennial Classic.
