How will the authorities reconcile that?
Similar to an ongoing thread concerning US dual nationals where US regulations requires US citizen to bear US passport enter/depart US, present both passports to the airline and let them figure out
their reporting requirements especially since you have no concerns about overstaying in Canada being a Canadian passport holder.
