I live in Toronto, Ontario, Canada, and I asked both the OPP (Ontario Police, which is the provincial police and equivalent to the state police) and the Toronto police and they both replied, with some hesitation and a tone that implied 'wtf, why are you calling me at 3:52AM to ask such a dumb question?' that it's OK. Actually, my question was 'is it illegal?' and they both replied "not that I'm aware of."
I'll take my chances. Should be safe.
