Narrative:
We where conducting the localizer approach to runway 6R in cyyz. We had started the approach at 3000 ft outside of lesod. When we past lesod we started down on our first step down to 1900 ft. As we started to come to 1900 ft the auto pilot went through 1900 ft about 300 ft low. My first officer disconnected the auto pilot and started to climb back up to 1900 ft. The controller came on and told us that we where getting kind of low to the ground and he asked if we where at 1900 ft on this section of the approach. I said that we where at 1900 ft as we where leveling off back at 1900 ft. We continued the approach as published and landed safely.we did our best and we caught the threat but I am going to be paying more attention to the auto pilot when we are conducting these step downs on a localizer approaches.
