The first known attempt to make glass in Canada began in 1819, when a German-born American entrepreneur worked for a year to establish a glass works at Rice Lake, Ontario, before his land grant was revoked and he abandoned the enterprise. The first recorded production of glass in Canada occurred in 1839 in the Mallorytown Glass Works, Ontario. Between 1840 and 1860, window glass and bottles were being made in five Canadian glass works in Quebec and Ontario. Window glass in Canada was first made in the 1850s in Quebec at the Canada Glass Works, Saint Jean, and the Ottawa Glass Works, Como. After 1880, new glass factories were established in Montreal, Wallaceburg (Ontario), and New Glasgow (Nova Scotia), with bottles, jars, and lamp chimneys their major products. By 1900, Canadian glass works were supplying about half of the Canadian market of 5.5 million people with bottles, lamps, and tableware. Most Canadian glass of this era consisted of pressed glass, machine-made glassware formed by pressure between a mechanically moving plunger and a mould. From 1839 to the present, glass works were established in forty-three Canadian communities from Nova Scotia to British Columbia. One of the largest was Dominion Glass with factories in Montreal, Toronto, Hamilton (Ontario), Wallaceburg, Winnipeg, Redcliff (Alberta), and Burnaby (British Columbia).
