The callback is related to the disability tax credit, which is the first that I mentioned. The idea is to call back the Canadian in two business days. It's not a precise time or day or schedule. It's within two business days. Those are happening. I believe that since that was launched at the beginning of September—I don't want to lead you astray—we've had maybe close to a thousand requests for a scheduled callback.
What we're seeing is that Canadians are calling because they want faster resolution of their file. We are offering the callback service to assist them from an eligibility standpoint and from a how-to-apply standpoint. However, it's certainly not necessarily resolving their cases more quickly, which is why we're also making great efforts to tackle root causes, as you mentioned in your question.
