Canada’s Navy is bigger than the Royal Navy. And the British army now actually has more Generals than it does battle tanks.
Britain realistically has no more “reach”. Their forces are a shadow of 25 years ago. Realistically they couldnt do the Falklands again. The best they coud do would be to play defense. Their Offensive capability is gone. No Carriers, No Harriers, No Vulcan strategic bombers. Nothing bigger than a Typhoon. They couldn’t strike the mainland except with sublaunched cruise missiles.
They have obviously decided that they will only send a few units of infantry and Helos to anything we do and will never fight big war again. Sadly, they are probably correct as they are flooded over with Muslims.
If by bigger, you mean "half the size", you are correct.
The bigger problem Canada's navy has is major Obsolescence , continual studies for replacements that never get built. The average age of major surface combatants is 23 years. None are younger than 17. They fly (when they can-reliability isn't great) the oldest SeaKings in the world, more than 40 years old,
