Ewww. Bring the eye bleach.
A few years ago I read an article or interview on this very topic, why haven't they upgraded to some other newer aircraft? The answer was basically they couldn't afford to. The Tutors sip fuel, are fully paid for, and at that time they had the parts and tools to keep them running for quite a while. If I remember right, they said if they upgraded to the CF-18, they would have to shrink the squadron to like 4 aircraft to maintain the same operating expenses.The pessimist in me thinks they'll disband the team when the Tutor is no longer viable.
