Heritage

The City was named after Sir John Thorold, a British Parliament member known for his sympathy towards United Empire Loyalists. Thorold experienced significant growth with the opening of the Welland Canal in 1829, which connected Lake Ontario to Lake Erie, boosting trade and industry in the region. Industries such as milling, shipping, and manufacturing thrived, shaping Thorold’s early economy. As a result, it became a village in 1850, then grew to become a town in 1875. It would be one hundred years before Thorold incorporated into a City. 

Thorold is becoming a popular tourism destination with the focus on three attractions in our City — cycling, Welland Canal and heritage. Studies show us that tourists are seeking out a cultural heritage experience. Many communities, have heritage conservation districts, (e.g. Niagara-on-the-Lake’s business area) which are designated under Part V of the Ontario Heritage Act, and which are a great attraction to visitors and tourists.

Learn about the history of Thorold by following one of three virtual tours on your phone. We offer a walking tour of our heritage homes in downtown Thorold, a driving tour around the rural areas of Thorold, and a cemetery tour exploring the famous people and darker stories of our ancestors who built our community.

The City of Thorold is situated on treaty land. This land is steeped in the rich history of the First Nations such as the Hatiwendaronk (Hat-i-wen-DA-ronk), the Haudenosaunee (Hoe-den-no-SHOW-nee), and the Anishinaabe (Ah-nish-ih-NAH-bey), including the Mississaugas of the Credit First Nation. There are many First Nations, Métis, and Inuit people from across Turtle Island that live and work in Niagara today.
