A plan was raised in the 1970s to add scheduled passenger service at the island airport by federal politicians. At the time, Toronto was a two-tier government. The City of Toronto was part of Metropolitan Toronto. Local opposition appeared to the plan to add planes to the airport. The City of Toronto opposed the plan, while Metro Toronto voted in favour. A compromise was reached in 1983 allowing only STOL type planes to use the airport with jets banned, and no runway expansion allowed.
