The St. Croix Soap Manufacturing Company was a Canadian business founded in 1878 in St. Stephen, New Brunswick by brothers James and Gilbert Ganong and Freeman H. Todd.
The brothers had earlier founded the Ganong confectionery company and in 1884 dissolved their partnerships with the result that James became sole proprietor of the soap making business.
James Ganong died unexpectedly at the age of forty-seven and his son Edwin took over the running of the business.
Advertising helped sell the company's products such as the innovative 1894 publishing of The Surprise Cook Book, a recipe collection by the then widely popular American writer Marion Harland.
