Why a Canadian carrier would probably follow Royal Navy design

What would an interwar Canadian aircraft carrier probably have looked like?

It would likely resemble a Royal Navy carrier because Canada and Britain would use the same core naval constructors.

An interwar Canadian carrier was unlikely to combine British and American practice into a unique hybrid. Canada would have drawn on the same core naval constructors who produced Royal Navy carriers. That shared professional base would push the ship toward British design solutions. The answer makes the available design institution, rather than national branding alone, the key constraint.
