@insidertoronto: Join our history club to learn about your city. Go to insidertoronto.ca Toronto's first regular island ferry service, launched in 1833, was a wooden "horse boat" powered by two to five horses walking on a circular deck treadmill connected to side paddle wheels. Crossing the harbor took about 30 to 40 minutes before steam-powered vessels replaced them around 1850. #toronto #torontohistory #islands #ferry #horses
