This is definitely a Horse Fly and it looks to us like Tabanus marginalus pictured on BugGuide, and it is very curious that though BugGuide states: “The most common biting horse fly throughout the world” there are only three images posted there and all are from a limited area in the Northeastern portion of North America, including Ontario.
