Caledonia Springs is now an unincorporated community in the northwest of the municipality of The Nation, Prescott and Russell United Counties in eastern Ontario, Canada.

Opening in the 1830s, it slowly grew from a simple structure to a very large luxury health spa and resort before closing in 1915.

The hotel spa complex and the supporting village, also largely owned by the CPR, boasted a variety of hotels, inns, boarding houses, churches, schools and commercial establishments and at its peak had a population of perhaps 500 to 1000 persons.

Though its customers came primarily from Montreal and Ottawa, people from as far away as New York and Europe came to enjoy the country and take the natural spring waters.

The various owners of the hotel and spring over its long history also shipped large amounts of its mineral water across Canada, to the US and to Europe.
