The Minister of Innovation, Science and Economic Development (French: Ministre de l'innovation, des sciences et du développement économique) is the Minister of the Crown in the Canadian Cabinet who is responsible for overseeing the federal government's economic development and corporate affairs department, Innovation, Science and Economic Development Canada. The Minister of Innovation, Science and Economic Development is also the minister responsible for Statistics Canada. By convention, the Minister of Innovation, Science and Economic Development also serves as the Registrar General of Canada.

The office of the Registrar General of Canada has traditionally been associated with the responsibility of overseeing corporate affairs, by virtue of its function in registering all letters patent. From Confederation to 1966, the Secretary of State for Canada was the Registrar General. Between 1966 and 1995, the office was held by the Minister of Consumer and Corporate Affairs.

The economic development function of the portfolio can be traced from the office of Minister of Trade and Commerce, which was created in 1892. The post of Minister of Industry briefly existed between 1963 and 1969 as a successor to the post of Minister of Defence Production. It was merged with the Trade and Commerce portfolio in 1969. The post of Minister of Industry, Trade and Commerce existed between 1969 and 1983. During that time, a separate post of Minister of Regional Economic Expansion (1969 to 1983)/Minister of Regional Industrial Expansion (1983-1990) also existed. In 1990, the post of Minister of Industry, Science and Technology was created.

From 1993 to 1995, a single minister was styled as Minister of Industry while concurrently holding the posts of Industry, Science and Technology, and of Consumer and Corporate Affairs, pending a government restructuring. The post of Minister of Industry was formally created in 1995. The office was renamed to its current name in the 29th Canadian Ministry.^[3]
