Joseph Hobson (1834–1917) was a Canadian land surveyor, civil engineer, and railway design engineer. He was the resident engineer during the construction of the International Railway Bridge and designed the first St. Clair railway tunnel. This was the first underwater railway tunnel between Canada and the USA and, when it opened in 1891, the first undersea tunnel linking two distinct countries and the longest undersea tunnel then constructed.
Early life and education
Hobson attended log schoolhouses in Guelph for his primary schooling. He then moved to Toronto and was there for seven years. He apprenticed with John Tully as a land surveyor. During this time he did layout plans for the Ontario towns of Kitchener and Guelph. Later he apprenticed under C. Schofield and he passed his final exam in 1855 for a provincial land surveyor.
Hobson in 1856 joined the firm of Gzowski and McPherson in Toronto. He returned to Kitchener in 1858 from Toronto to work for the county of Waterloo as their engineer on a part-time basis. Besides being the county engineer he also did private surveying. One of his contracts was the surveying of the township of Bidwell on Manitoulin Island.
Hobson was later an assistant engineer on the construction of the Grand Trunk Railway from St. Marys to Sarnia. He was also engaged in railway surveys in Nova Scotia and also in the United States. Hobson lived in Guelph from the mid 1860s to the mid 1870s. From the summer of 1869 to the spring of 1870 he was an engineer to George Lowe Reid, chief engineer of the Great Western Railway. He assisted in the building of the Wellington, Grey and Bruce Railway from Guelph to Southampton.
Construction of the International Railway Bridge, across the Niagara River between Fort Erie, Ontario and Buffalo, New York, was contracted out in 1870 for a cost of over $1 million. The bridge was about a half mile long. The engineer-in-chief was E.P. Hannaford. Hobson was the resident engineer and lived onsite. When this project was done at the end of 1873 Hobson was promoted to chief assistant engineer of the Great Western Railway and further promoted to chief engineer in 1875. He moved to Hamilton, then. In 1882 he became chief engineer of the Grand Trunk Railway west of Toronto.
Hobson was appointed in 1886 to design and build the St. Clair Tunnel between Sarnia in Ontario and Port Huron, Michigan. The tunnel was constructed within a year and the first trains ran through in the later part of 1891. It was then the first undersea tunnel linking two distinct countries, and the longest then constructed, at 6,025 feet portal to portal. Total length of the tunnel counting the approaches was 11,500 feet. The cost was over $2.5 million. After this project Hobson became chief engineer for the entire Grand Trunk Railway in 1896. The tunnel was converted to run electric trains in 1908.

Hobson married Elizabeth Laidlaw of Guelph in 1856. They had two sons and four daughters.

The first underwater railroad tunnel to a foreign country was the St. Clair Railway tunnel between Port Huron, MI, and Sarnia, Ontario, Canada, which was opened for freight traffic on September 19, 1891, and for passenger traffic on December 7. The tunnel was designed and built under the supervision of Joseph Hobson, chief engineer of the Grand Trunk Railway (later the Canadian National Railways), at a cost of $2.7 million. Its length from portal to portal was 6,025 feet. The tunnel was equipped with electricity on May 17, 1908.
