Buck and doe's in ontario- need help with rules/laws

Trying to figure out a date to host it. Some people say St.Patty's to early to have it since not getting married till September. just thought theme be fun. My FH wants it in June but I don't want to clash with weddings maybe we could do the first weekend? I am also having concerns with rules of buck and does. they have changed a lot in Ontario. Some places all different rules and I found a place that doesn't have any of them. i'm just not sure if they aren't uptodate on laws? All places have told me (except this one) we can't do any games of luck or chance (twoonie toss, 50/50 raffle, wheel of fortune). the only thing your allowed to do is games of skill example the nails in a board or throwing a hay ball and silent auction games. I have also been asked for a guest list up to a week before from all venders except this one. are these actual laws or just rules most places are following?
