Cornwall is a city of about 48,000 people (2018) on the St. Lawrence River in Eastern Ontario.
Cornwall sits on the banks of the St. Lawrence River, offering a convenient launchpad for exploring the wider canal‑rich region of eastern Ontario. Visitors can park near the waterfront and hop on the historic Cornwall Canal boat tours, which thread past 19th‑century lock structures still in operation. The city’s relatively flat streets make it cyclist‑friendly; a short ride upstream brings you to the scenic Gananoque and the Thousand Islands, while a quick drive west opens the scenic Rideau Valley. Because the town lies on the Canada‑US border, a day trip to upstate New York is a seamless addition, especially for those keen on contrasting the rural charms of both sides of the river.
The most rewarding period to visit Cornwall is late spring (May‑June) or early autumn (late September‑October). During these shoulder months the river’s fog lifts early, giving photographers a clear view of the historic downtown brick facades. Local markets, such as the weekly farmers’ bazaar on Victoria Street, brim with produce from the surrounding orchards, providing a taste of the region’s apple and vineyard output before the summer crowds arrive. Evening temperatures stay mild enough for a stroll along the historic Fort Cornwall site, where the occasional acoustic gig by a local folk group adds a community‑driven soundtrack to the historic backdrop.
Most guidebooks skim past Cornwall’s industrial past, yet the city’s streets are a living museum of early Canadian manufacturing. A self‑guided walk begins at the former Imperial Oil refinery, now repurposed as a public art space, and continues to the old Cornwall Power Plant, where interpretive panels explain the evolution from coal‑fired boilers to modern hydroelectric projects. Hidden in plain sight are the brick kilns that once produced the region’s famed lime, now visible through the cracked façades of the old warehouse district. Stop at the small heritage centre on Oxford Street for a short video on the town’s role in the Underground Railroad, adding a poignant layer to the industrial narrative.

Please note that there are many more specific templates. Please use {{R from alternative spelling}}, {{R from alternative hyphenation}}, {{R from alternative punctuation}}, {{R from alternative spacing}} and {{R from misquotation}} where relevant; see subcategories of Category:Redirects from modifications for other options (capitals, abbreviations, diacritics, plurals, stylizations, transliteration, ligatures, different parts of speech, etc.). If you are unsure which to use, this template is fine; someone will make it more specific later if necessary. In cases of modification from distinctly longer or shorter names, please use {{R from long name}} or {{R from short name}}, respectively. In mainspace, an abbreviation should be tagged with {{R from initialism}} or, if it can be spoken like a word such as NASA and RADAR, use {{R from acronym}}. Use this rcat instead of {{R from other capitalisation}} and {{R from plural}} in namespaces other than mainspace for those types of modification. This may also apply to several other subcategories of modification; please check those templates' output before saving if using outside of mainspace.
