What if Canada began building one Tribal-class destroyer per year in Halifax from the 1935 budget?
Short answerCanada gains four useful destroyers and a stronger naval industrial base, but the force is too small to alter the war strategically.
NotesA 1935 start could deliver roughly four additional destroyers before the war. They would enlarge the Royal Canadian Navy and force earlier development of skilled labour, yard organization, and naval support infrastructure in Halifax. Operationally, the ships might reinforce the North Sea or Norwegian campaign. Their local effect could matter, but the number is too small to change the wider war by itself. The industrial learning may be the more durable consequence.
