Keep mowing as long as the grass is still growing. That usually slows down once daytime temperatures stay below 10°C, often late October in the GTA. On the final cut, go a little shorter than usual, around 2 to 2.5 inches. Long grass left under snow mats down and invites snow mould by spring. One more thing: clear the leaves before that last mow. Leaves left on the lawn over winter smother the grass underneath.
