Copp Clark’s authority began with reference publishing and continues today through financial market data used across global operations.
Founded in Toronto Copp Clark traces its origins to Hugh Scobie’s Toronto publishing, printing, bookbinding, lithography, and stationery business.
First Canadian Almanac Published Scobie, in partnership with James Balfour, published the first Canadian almanac, establishing an early legacy in trusted reference publishing.
The Copp Clark Name Takes Shape William W. Copp and Henry J. Clark obtained control of the firm’s interests and built Copp Clark into a major publishing enterprise.
