Could Canada operate three 40,000-ton carriers?

Could Canada operate three small carriers of about 40,000 tons each?

Yes if it chose to prioritize and structure naval investment around them, but current governments prefer other spending.

National capacity and current policy point in different directions. Canada's economy and government budget are large enough that operating three small carriers is conceivable. The constraint is that the government assigns higher priority to other spending. Carrier ownership would therefore require procurement money and a structured choice to fund the fleet, personnel, aviation, and supporting infrastructure over time.
