In quebec, its the kiss on both cheek when coming and going from male (on female) and in between female, less hugs though except if you haven't seen the person in awhile and that person's close.
I find this funny, guys just love this tradition of kissing the cheeks, while I am ambivalent about it, many men have rought beards, bad breath, bad skin, etc. From a few feet its ok, but up close.... Ewww. But, if the guys attrative and smells nice... I do like the kiss :-).
