Pièce 0115 - Letter, with enclosure, Toronto, to Michael

Macmillan of Canada was a Canadian publishing house.

The company was founded in 1905 as the Canadian arm of the English publisher Macmillan. At that time it was known as the "Macmillan Company of Canada Ltd." In the course of its existence the name changed to "Macmillan of Canada" and "Macmillan Canada".

Macmillan of Canada was sold to Maclean-Hunter in 1973, who, some seven years later, sold it to Gage Publishing.

In 1998 Macmillan Canada, as it was then known, became an imprint of CDG Books, which was formed as a joint venture of Gage and US publisher Hungry Minds. CDG was purchased in 2002 by John Wiley & Sons, who had acquired Hungry Minds the year before. At this time Macmillan Canada ceased to exist either as an imprint or a publishing house.
