Campbellville Station was built by the Credit Valley Railway in 1879 whilst its line between Toronto and St. Thomas was under construction. The first revenue passenger train left Campbellville for Toronto on September 1st, 1879 ahead of the first annual Toronto Industrial Exhibition. However, regular service would not commence until September 15th. Service was extended west of Campbellville to St. Thomas in 1881, and by October 1883 the station saw a total of eight passenger trains per day. The Canadian Pacific Railway gained control of the Credit Valley through one of its proxies, the Ontario & Quebec Railway, in November 1883.

In 1888, the Guelph Junction Railway was opened between Goderich and a point on the former Credit Valley line just 2.2 kilometres west of Campbellville, which became known as Guelph Junction. The GJR was immediately leased by the Canadian Pacific Railway and the new station that was built at the junction quickly overshadowed the one in nearby Campbellville in terms of importance. By 1899 service to Campbellville Station had been reduced to just three trains per day. To allow for a higher volume of trains on the former Credit Valley line, a second main track was laid between Toronto and Guelph Junction during the mid-1910’s. The original Credit Valley station at Campbellville was replaced during this period. The new station followed a standard design that was very similar in size to its predecessor. It had a single storey with a wooden exterior and a bay window facing the tracks. A single chimney protruded from the middle of the hipped roof.

Service to Campbellville would creep up to seven trains per day by 1921, though it would never again reach the level of service it had before the Guelph Junction Railway was created. The Great Depression would cause almost all remaining service to evaporate, save for a single eastbound train from London that would only stop at Campbellville if flagged down. The popularization of automobiles and air travel during the postwar era would lead to a significant decline in passenger ridership across Canada. What little ridership Campbellville Station saw during this period was likely further reduced with the completion of Highway 401 just north of Campbellville in 1960. The station would be closed to passengers by 1961, although the building would remain and be used by Canadian Pacific in some other capacity. It remained on the station index of Canadian Pacific timetables until 1970.
