Hello! Thank you for your question.
Corning Glass Works of Canada Limited (Leaside, Ontario)
According to a short article in the Canadian Depression Glass Club Review, vol. 31, no. 3 (July to Sept 2008):
In 1945 Corning glass Works of Corning, New York set up a Corning plant in Toronto, Ontario. The Federal charter creating Corning Glass Works of Canada Limited (as a private company) was issued on June 8th, 1945. The factory was located at 135 Vandershoof Avenue in Leaside. Production of glassware actually did not begin until June 22nd, 1946. Along side their Corex tableware, Corning also produced tableware in pastel blue (what collectors nowadays refer to as "Piecrust") and turquoise ("Crown"). These tableware lines were discontinued by 1954.
Example of Delphite Blue Pyrex
The collection of the Museum of American Glass in West Virginia includes a delphite blue sugar and creamer set (ca. 1950) by Corning Glass Works of Canada. The description of the set cites "Canadian Depression Glass," by Walter Lemiski, M.A., available online at https://www.antique67.com/articles/depressionglass/depressionglass.php (as of April 17, 2019).
