Is Canada still sovereign?
must be, Russia still wants to invade us
They like to think so. In reality they are America’s Toupee.
Canada is not and has never been a sovereign nation. Canada, like Australia and other commonwealths of the Crown, has a governor general who represents the King.

The following are among the responsibilities of Canada's governor general, all of which are undertaken in the name of the King:
-representing Canada abroad
-signing treaties and declarations of war
-The governor general is also Commander-in-Chief of Canada.
The governor general has important parliamentary responsibilities:
-summoning, proroguing and dissolving Parliament (yes, the Crown can dissolve the Canadian Parliament)
-giving Royal Assent, which brings parliamentary bills into law (nothing becomes law in Canada if the Crown doesn't give assent to it)
The governor general is also the Commander-in-Chief of Canada. (The Crown determines where, when, and against whom the Canadian military is deployed).
There's nothing sovereign in any of that.
