"Both Richelieu and Jean Bart were very modern and very capable ships. Some rate them as superior to the Bismarck and Tirpitz."
They might have been when facing the enemy - but with their entire main armament mounted forward, they'd have had a hell of a time countering fire from an enemy coming up astern, same as the Royal Navy's Rodney and Nelson. Of course, they could have turned broadside-on to fire but that would have denied them the full benefit of their high maximum speed when escaping from superior forces.
Without looking it up on the WWW, number of Tribal Class destroyers operated by Canada during WW2: eight. Number of Flower Class corvettes built in Canada during WW2: 42. I presume most if not all served with the RCN and I know four 'Modified Flowers' were transferred from the ten built in the UK for the Royal Navy.
