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