Apple trees were introduced to
Canada at the
Habitation at Port-Royal as early as 1606 by French settlers. Following its introduction, apple cultivation spread inland. The McIntosh's discoverer,
John McIntosh (1777 – ), left his native
Mohawk Valley home in New York State in 1796 to follow his love, Dolly Irwin, who had been taken to
Upper Canada by her
Loyalist parents. She had died by the time he found her, but he settled as a farmer in Upper Canada. He married Hannah Doran in 1801, and they farmed along the
Saint Lawrence River until 1811, when McIntosh exchanged the land he had with his brother-in-law Edward Doran for a plot in
Dundela. While clearing the overgrown plot, McIntosh discovered some apple seedlings on his farm. Since the crabapple was the only native apple in North America before European settlement, it must have had European origins. The Snow Apple (or Fameuse) had been popular in
Lower Canada before that time; the seedlings may have sprouted from discarded fruit. Fall St Lawrence and Alexander have also been proposed, but the parentage remains unknown. The McIntosh made up 40% of the Canadian apple market by the 1960s; and at least thirty varieties of McIntosh hybrid were known by 1970. However, its market share declined to 28% in 2014 Its popularity has also waned in the face of competition from imports; in the first decade of the 21st century, the Gala (imported from Chile or the United States) accounted for 33% of the apple market in Ontario to the McIntosh's 12%, Production remained important to Ontario, however, as of McIntosh apples were produced in 2010. In Quebec, about two fifths of all apples harvested were McIntosh, as of 2020. Production remained relatively high in part because many orchardists were at the end of their careers with no successors, and as such were not keen to replace the McIntosh with newer varieties. which do not require royalties for cultivation and sales, unlike the newer managed varieties. In the United States, the McIntosh was one of the most produced apples during the twentieth century, behind only the
Red Delicious and the
Golden Delicious. In the Northeastern United States, the McIntosh replaced many
Baldwin trees that were killed in a severe winter in 1933–34. The McIntosh become the second most popular variety in the 1970s, after the Red Delicious. By the 2020s, however, total production of the McIntosh, measured in
bushels, has fallen behind that of a new variety, the
Cosmic Crisp. Even in New York, which has traditionally favoured the McIntosh, production has fallen from about a quarter of the state's total volume in the 1980s to about 14 percent in the 2020s. The decline of older varieties like the McIntosh and Red Delicious follows the advent of newer varieties like the Honeycrisp, offering consumers sweeter and more complex tastes. They also risk becoming mere commodities—that is, common and cheap products—making it them less profitable for farmers and distributors.
