No, there are no similar cases where the defence provided under section 43 was selected and applied.
However, there have been situations in which the defence claimed that the force used wasn't that excessive. I can even use the example that you cited and that occurred in the Ontario Court of Justice in December 2023. It was a case of contradictory testimony. Some witnesses claimed that the child had been aggressively grasped by the wrists, that they had seen a wave of frustration cross the accused's face and that he seemed to be angry. Other witnesses, including the accused, claimed he had acted appropriately and properly.
I may not have seen all the judgments, particularly since many of them aren't written down. However, in all of the ones I've seen, anger and frustration levels never exceeded the limit prescribed by section 43.
