Mont Saint-Grégoire (height: 251 m (823 ft)) is a mountain in the Montérégie region of southern Quebec. The mountain is composed of essexite and syenite, strongly contrasting with the surrounding sedimentary rocks. The area around Mont Saint-Grégoire is known for its maple syrup production, plus some wine as well.

The name was changed in 1923 from Mount Johnson.

Geology

Mont Saint-Grégoire might be the deep extension of a vastly eroded ancient volcanic complex, which was probably active about 125 million years ago.^[1] The mountain was created when the North American Plate moved westward over the New England hotspot,^[1] along with the other mountains of the Monteregian Hills. It forms part of the vast Great Meteor hotspot track.
