If it's any consolation, there is in fact runway construction taking place this summer at YYZ, and runways have been / are closed for that. If you had a strong belief / evidence the delay was misclassified, you're able to pursue your claim with the CTA or in court. At this point it's pretty hard to easily find public information about the reason for the cancellation to say either way.
If you haven't already submitted a claim to AC, you could write in to customer relations and see what they have to say. (And maybe provide you with a goodwill gesture)
