September 11, 2019
Parliament was dissolved on September 11, 2019, and prorogation was not used by the Liberal government during the course of their mandate. Therefore, this promise is marked as achieved. Of course, one could argue about the value of such a promise in the context of a majority government. This promise was made as a direct reference to the 2008–09 Canadian parliamentary dispute, during which Stephen Harper prorogued parliament to avoid his minority government being defeated by a motion of non-confidence.
