Altona is a ghost town located in Pickering, Ontario, at Sideline 30 and the Pickering-Uxbridge Town Line. It is just east of Whitchurch-Stouffville, and was named after Altona, now a borough of Hamburg, Germany. The first schoolhouse was built in 1834; in 1856 there were 256 inhabitants, "unable to read and write, about 30%." By 1869 the hamlet had 200 residents and a regular stage coach to Stouffville and Toronto. In 1910 there was still a daily stage to Stouffville, but Altona's population had fallen to only 100 people.
