The Trent-Severn Waterway is a 386-kilometre (240-mile) canal route that connects Lake Ontario at Trenton to Georgian Bay in Lake Huron at Port Severn through 46 locks, following the same rugged route taken by Samuel de Champlain in 1615. Begun in 1833 primarily as a safe passage for ships on the Great Lakes against possible American attack, the waterway would soon prove its value as a system of transportation for goods as well and would become an economic boost for the nation. Lured by the promise of free land, thousands of British, French and Italian men came to Canada to build the canal. The first lock was built in Bobcaygeon in 1833, but the entire canal wasn’t completed until 1920 – 87 years later. Today, the canal is run by Parks Canada and is a recreational boater’s paradise that attracts 18,000 visitors from across North American each summer.

Two prominent men – Eben James and William Fraser – had tremendous influence on the development of Trenton through their lives and their rivalry, establishing a company that would influence the development of the town more than any other company in its history. By the 19th century, Trenton was becoming a central hub of agriculture distribution in Ontario. James and Fraser took advantage of this factor by establishing Trenton Cold Storage, using the region’s expanded train and steamship networks to distribute produce more effectively to regional, national and international markets. And apples made up a large part of that produce. The influence of this company and these two men has left an enduring legacy that resonates in the town today. Learn more about their lives and their company through the Sean Scally video below – entitled Apples and Egos: The Saga of Eben James and William Fraser – and see for yourself how apples and egos impacted the history of Trenton.

This park, created by the Town of Niagara-on-the-Lake, helps us understand, celebrate and honour the town’s Black history. It is an experiential art installation designed to engage, educate and challenge visitors. The park has an accompanying audio/visual walking tour that you’re welcome to explore. During Doors Open, the Niagara-on-the-Lake Museum's "Tiny Museum" will also be onsite with a mobile exhibition.

The Belleville Wastewater Treatment Plant is located by the Bay of Quinte in Belleville’s east end. It deals with wastewater that goes down drains in our homes, public buildings and commercial facilities. Wastewater travels through the city’s sanitary sewer system to the Water Pollution Control Plant at the same complex. Wastewater then goes through an extensive treatment process and is returned to the Bay of Quinte. Biosolids are used as fertilizer for agricultural purposes. As of 2020, city water staff have been testing a new odour-control product to break down and control sulfur compounds that can fill the autumn air surrounding the city’s wastewater treatment plant. A storm sewer is a pipeline designed to direct stormwater to a stormwater management pond or receiving stream or body of water. Stormwater is rainfall and melting snow that soaks into the ground or runs off surfaces into storm sewers and nearby waterways. As part of Digital Doors Open, learn more about this treatment plant here.

Westfield Heritage Village, a living history museum, consists of over 35 restored historical buildings dating from the early 1800s. Various building types are positioned as a small village within a natural conservation area of over 202 hectares (500 acres). The village was started by two high school teachers – D. Glenn Kilmer and Golden L. MacDonell – who purchased the original 12-hectare (30-acre) site to create an outdoor museum preserving 19th-century rural life. They purchased their first building, the Jerseyville Train Station, outbidding a local farmer who wanted it for his farm as an outbuilding. Six more buildings were added before it was officially opened in 1964. Some 30 buildings later, the village is a thriving cultural centre that features educational programs and events year-round. Take a virtual tour of this spectacular site in the video below.

Come and visit this beautiful national historic site, Willowbank, which was built in 1834-36 in the Greek classical revival style. Since 2006, Willowbank has been home to the School of Restoration Arts.
