Masco Electric Company tenure
Advertisements for the Masco Electric Company appear as early as 1950 in Toronto newspapers. On 5 July 1951 Masco published an advertisement in the Globe and Mail announcing their move to 54 Duke Street. Their first appearance in a city directory is 1953, and their last is in 1963. The 1964 Toronto City Directory lists the site as vacant.
