It goes without saying that Toronto's waterfront has transformed dramatically over the past century, and what was once a gritty industrial corridor filled with active piers, docks, and factories is now lined with green spaces, condo towers, and plenty of restaurants.
Before the 1920s, the Esplanade was the city's southernmost street, but as Toronto rapidly expanded, a massive infill project pushed the waterfront further down south, allowing Queens Quay to be built as an access road for the inner harbour's ports and slips.
Before we delve into its history, we can't proceed without acknowledging that Queens Quay (not Queen's Quay) is arguably one of the city's most commonly mispronounced streets. Despite its spelling, "quay" is pronounced "key," which is a reference to the street's origins as a waterfront wharf.
For most of the 20th century, the waterfront area remained focused on trade and industry. Between Yonge Street and Parliament Street, Queens Quay was home to numerous buildings connected to shipping, including the Redpath Sugar Refinery.
It wasn't until the 1970s that the street began its transformation into the neighbourhood we recognize today, with developments like the Toronto Star building, which officially opened in 1971, and the Westin Harbour Castle in 1975.
A lot has changed since the 1920s, so let's take a step back in time to see what Queens Quay used to look like in Toronto.
