Pro Swing Inc v Elta Golf Inc 2006 SCC 52 is a leading Canadian case decided by the Supreme Court of Canada on conflict of laws.

Pro Swing is an American company that sells golf equipment under the "trident" trademark.

A settlement was reached which ordered Elta Golf to refrain from selling any products with the trident logo.

Pro Swing then filed in the Ontario Superior Court of Justice for enforcement of the order.

She further advised in obiter that courts should ensure there will be no conflict once the order is rendered and should not allow punishments that are not available under the foreign jurisdiction.
