Before Long Branch became a village, it was the home of Loyalist Col. Sam Smith in the late 1700s. In the 1880s part of Long Branch was to be developed as a summer resort called "Sea Breeze Park", later to be renamed Long Branch Park which is still there today.
After the Second World War, Long Branch saw an influx of immigration. This resulted in the construction of one of the largest Orthodox churches in Canada; St. Demetrius.
Long Branch is currently comprised of a low rise commercial district along Lake Shore Blvd. W. The rest of the neighbourhood is mostly comprised of single family homes with a particular cottage feeling clearly evident in the character.
