The apparent quality gap between Canadian and British escorts partly comes from comparing unlike missions. Britain possessed high-performance fleet destroyers, but most of those ships operated with major fleets rather than on routine convoy duty. Both navies entered the war short of purpose-built convoy escorts because interwar governments had neglected that category. When Canada later acquired Tribal-class destroyers, their capabilities brought correspondingly dangerous assignments rather than ordinary escort work.

Why escort comparisons can mislead
Canadian convoy escorts should be compared with the Royal Navy ships doing the same work, not with fast fleet destroyers assigned to higher-threat operations.
