In the last 100 years, there have been many subway proposals that have come and gone. One of the first serious proposals, in 1911, would have seen streetcar subways built under Yonge, Queen and Bloor streets to feed city and interurban cars downtown. Later proposals called for a Queen Street subway for streetcars or heavy rail, which remained on the books until about 1980. The Eglinton West subway even started construction, until filled in by order of the Harris Conservatives in 1995. Another serious subway proposal that never got anywhere was something called the Downtown Relief Line.
