No, it depends on the rink rats running each pad. But it is city wide policy for insurance reasons (keep the puck down, no slap shots, that kind of thing). Only helmets are mandatory, and most guys only wears skates, helmets and gloves.... no cups, shinpads, etc. Goalies attract testosterone you know.
The key then would be stay away from High Park and other high traffic pads (especially those having a public skating pad beside the hockey rink... public skating attracts moms and kids, which attract strict attention to the rules from the rats), ...and seek out some of the other rinks suggested here.
BTW, there's a lot of pick up hockey in rinks all over the city... usually late night (10 pm start or later) or early morning hockey. There's ALWAYS guys looking for goalies or back ups if their regulars can't make it. Put you name and phone up in the five closest rinks to your house and I guarantee you'll get calls to come out play. Be clear you haven't played in awhile, but trust me they won't care, they just want to have someone to shoot at. It will cost you nothing (goalies don't pay) and you'll probable get a free beer or two out of it afterwards.
