American courts are not bound to follow any Canadian rulings. They can choose to cite anyone who agrees with them as support for their position, no matter who it is, though. So they can certainly write something saying "look, everyone else agrees with us too" but this is not at all the same as when they're trying to act according to the past decisions of the courts that supervise them. In one case, they're just looking for people who agree. In the other case, it's more or less mandatory. Yes, they can try to avoid following the precedent if they want, but the judges who supervise them can overrule them if they're out of line.
