Prime Minister Stephen Harper is proroguing Parliament through a request to the Governor General.

And I feel strongly there is a constitutional argument that no IGA or any other international agreements shall be signed prior to the next Throne speech in October. Some including many in the government might feel differently but there is a strong case that Harper right now is only a “caretaker” government.
One very real consequence is even after they sign an IGA(or any treaty) it must be put before Parliament for 21 sitting days prior to any further action that can be taken to ratify. If they were to sign an IGA lets say tomorrow the 21 sitting days of Parliament would only start whenever Parliament comes back(October??). If October 21st were to be the return of Parliament and a throne speech the government can’t introduce legislation to ratify and implement an IGA until November 26th which brings us pretty close to the Winter recess.
