In 2014, an announcement was made to amalgamate Midland SS and Penetanguishene SS. This decision was made due to the declining enrollment of both schools. PSS closed at the end of the 2015–16 school year, its 350 students joined the 500 students at the existing MSS building, which can accommodate up to 1,400 students, while construction of the new school takes place. Construction began in the spring of 2016, and was expected to be complete and opening in September 2018, however, in July of that year it was announced that it would not be ready. A new completion date was not provided. February 4, 2019 was the first day for students in the new GBDSS building.
