I was actually looking into the Troodon with a dagger-style blade.
However the legality of simply owning an Auto is unknown to me right now. I can't imagine Auto's being fully prohibited in Ontario, Canada.. But I don't know.
In Canada a double-edged blade is viewed as a weapon rather than a tool and autos (if you mean switchblades or stilletos) are flat-out illegal and won't make it through customs. You may want to think about that before choosing to pack one around
