It was a thriving commercial center of more than 3000 people. The town was officially incorporated in 1874 and although a devastating fire in 1876, burned many of the original buildings downtown, a modern commercial centre sprang from the ashes almost immediately. Many of the fine commercial buildings in Seaforth were constructed in one great building boom that began in 1877. The Cardno Music Hall and tower is one such building. Numerous designated heritage homes dating to the late 19th century also attest to the economic stature of Seaforth in its early days.
Today there are many fine modern homes in a very pleasant, small town atmosphere.
