Mr. Speaker, any lawyer knows that a contract is completed with the consent of the parties. This is something known to every lawyer. When there is mutual consent, the sale is complete.
In Quebec, this applies even to real estate transactions. In Ontario, this does not apply to property, but it does for other personal property.
Everyone knows that. You pick up the phone. You call your broker and tell him to buy or sell shares. There is no contract, but you have to pay if you have told him to buy or sell shares.
