The building was previously home to a women's college, and Ottawa Tech moved into the space in 1916.
aIn the 1970s, Ottawa saw a decentralization of education which drew students to the newer suburban schools.
During this time, the school's academic performance diminished, with only 10% of students continuing to university upon graduation.
The five-acre (20,000 m2) campus now houses many different tenants offering training and high school programs.
Despite pressure to sell the buildings, which were valued at over $10 million in 1999, the site is still owned by the Ottawa-Carleton District School Board.
