Politics
Snow was elected to the Ontario legislature in the 1967 provincial election defeating Liberal candidate Robin Skuce by 164 votes in Halton East. He served as a backbench supporter of premierJohn Robarts for the next four years. In 1967 he introduced a resolution urging the province to adopt Canada's national building code. On March 1, 1971, he was named a minister without portfolio when Davis replaced Robarts as Premier. He was re-elected with a much increased majority in the 1971 election. He was promoted to Minister of Public Works and Minister of Government Services on February 2, 1972. The Progressive Conservatives were reduced to a minority government in the 1975 election. Snow was re-elected in the redistributed riding of Oakville, and was promoted to Minister of Transportation and Communications on October 7, 1975. During his time as minister, he introduced mandatory seat belt legislation for adults and child restraint seats for children. In 1981, he approved the extension of Highway 404 before the completion of an environmental assessment. Even though his deputy minister claimed responsibility, he personally paid the $3,500 fine. In 1983, he pushed for the construction of a 3.4 kilometre highway linking his home town of Milton to Highway 401. He claimed that it was needed to increase industrial development. Snow supported Frank Miller to succeed Davis as party leader in January 1985, and was retained in Miller's portfolio as a minister without portfolio responsible for Urban Transit. He retired from politics in 1985.

Later life
Snow self-published an autobiography after leaving political life, and purchased a golf course in Hornby, Ontario. He donated his family wheelchair van to the Lions Foundation of Canada in August 2005. In 2006 Snow and his wife Barbara donated half-a-million dollars to the Milton District Hospital Foundation's CT Scanner Campaign. The complex housing the scanner is named the "James and Barbara Snow Family Trust Diagnostic Imaging Annex". The town of Milton, Ontario renamed Fourth Line James Snow Parkway, with initial approval for an interchange with Highway 401 coming in 1979. It was upgraded in the early 1980s to become a major arterial road, and is in the process of being extended on both north and south ends. The overpass of the James Snow Parkway at Highway 401 was damaged in 1986 when it was hit by a fuel tanker that caught fire, necessitating that the bridge deck be entirely replaced. It was renamed after James Snow paid to pave the road extended over the 401 so he could get home faster. Snow died on September 13, 2008 of complications from diabetes. He was 79.
