The Hotel General Brock opened on July 1, 1929.

It was named for Major-General Sir Isaac Brock, who died in the War of 1812, while defending Canada from the invading Americans at the nearby Battle of Queenston Heights.

The 260-room General Brock was designed by architects Findlay and Foulis and constructed at a cost of $1.5 million by The Pigott Company of Hamilton, Ontario.

In 1959, a new $500,000 convention wing was added, including the hotel's Crystal Ballroom.
