I read in another thread that someone said it is code in Canada to have the incoming gound wire bonded to the box in a receptacle, as opposed to the outgoing. I guess it could be for lighting or whatever

I can't find the thread, but can anyone confirm that this is code or not? I don't see it in my Knight book.

Does not matter, all the grounds in the box should be tied together.

I usually take one ground to the screw and then tie the rest together.

Not sure I understand your question. Metal boxes need to be bonded to the ground. Normally in metal boxes there are enough screws to bond all the grounds to the box and leave one of them long enough to ground the receptacle. It doesn't matter which one. Ground screws in metal boxes have a raise spot beside them to allow you to put one ground wire under each side of the screw. They do not have to be wrapped.
