It's common practice on bare copper grounds to just twist them together, and then trap one or both under the screw - but that doesn't work with the stranded and insulated ground.
Basic Grounding Wire Question in Receptacle Box - Please Help.

I remember back in the day taking receptacles out and just finding the grounds spliced as normal but with no wire nut at all, just wires twisted together. I always thought that was a little cheezy, was that acceptable by code at one point in time, or was I just looking at shoddy work?

Unless you are using steel or brass switchplates...

In the US it is not acceptable to put 2 wires under a screw. It is also not acceptable to twist ground wires and not use a wire nut. Far as I know neither has ever been code compliant.
Shoddy work.
Metal switch plates is the reason the ground requirement was added. A ground wire is required with plastic boxes.
AFAIK it is still acceptable on bare copper ground wires.
And you like almost burning your fingers on the plate - - - - - - . The metal box acts as an enlarged heat sink
I don't believe canada was ever that backward.
