We're definitely building on the improvements and the lessons learned over the past three years, and we have been for some time. In fact, I'm not sure the work ever stopped from last season. We've been preparing for this upcoming season. CRA, TBS, unions and employees themselves have all been very focused on ensuring that we address any potential issues with T4s, whether it be employees identifying overpayments or anything else.
Les, is there something you'd like to add?
