There are two: investor and state dispute processes, as well as state-to-state. Under the state-to-state process, a party country challenges the measure it alleges is inconsistent with the applicable trade rules. If the panel finds that a violation has occurred, Canada would have to bring its laws into compliance, or the affected party may ultimately suspend benefits provided to Canada by the applicable agreement--for example, raising tariffs or eliminating reductions in tariffs.
The second process I mentioned is investor and state. In this situation an investor brings a claim for damages resulting from the measure it alleges is inconsistent with the applicable rules. In this instance, a trade panel decision is binding and it may award damages and applicable interest and restitution of property. Of course these can be quite detrimental to Canadian industry.
