In the late 1800s, lumber companies were plowing through the old growth forests of Ontario, making and breaking towns and villages. Trenton was no different. In 1852, Gilmour and Company constructed a sawmill at the Trent Port along the Bay of Quinte. David Gilmour arrived in Trenton in 1879 to take over the mill operation, both expanding and mechanizing the business to take advantage of the plentiful supply of trees that made its way down the Trent River. To accompany their growing workforce, the company also built new homes in Trenton. Despite a devastating fire, Gilmour continued to grow his business. The Gilmour Mill had a huge impact on the expansion of Trenton, becoming the largest sawmill in the world. Its effects are felt still today. Watch the documentary below, by Sean Scally – entitled Lumberbaron: The Gilmour Years – and discover the story about the effect of the Gilmour Lumber Company on the region from Trenton to the Muskokas.
