The Provincial Agricultural Association and the Board of Agriculture for Canada West inaugurated the Provincial Agricultural Fair of Canada West in 1846, to be held annually in different localities. For the 1858 fair, to be held in Toronto, a permanent "Palace of Industry" exhibition building, based on London's Crystal Palace, was built at King and Shaw Streets in what is now Liberty Village. The site held four more fairs until the 1870s when the City of Toronto government decided the exhibition had outgrown the site. The City signed a lease with the Government of Canada for a section of the western end of the reserve in April 1878. The Palace of Industry was moved to a site on the reserve near today's Horticulture Building, reconstructed and expanded. The City sold the King and Shaw site to the Massey Manufacturing Company.
