Our Variety Assessment

Its strengths, growing requirements and the conditions in which it performs best.

Ontario is a large, late Canadian apple with juicy, sharp and lightly aromatic flesh. It is suitable for fresh eating and juice but is particularly good for cooking, breaking down into an excellent purée. The apples store well but bruise easily. As a triploid and poor pollinator, the tree requires two other compatible apple varieties nearby.
