The Financial Administration Act allows the Governor in Council to ask the Governor General to issue a Special Warrant permitting the Government to make charges on the Consolidated Revenue Fund not otherwise authorized by Parliament, provided the following conditions are met:
Special Warrants may be used only from the date of dissolution of Parliament until 60 days following the date fixed for the return of the writs after a general election.
No Special Warrants may be issued during a prorogation of Parliament.
The Financial Administration Act requires that every Special Warrant be published in the Canada Gazette within 30 days of its issue. Notification of the amount authorized under such a warrant must be tabled in the House within 15 days of the beginning of the next session of Parliament.
Retroactive parliamentary authorization of the warrant is provided in the first Appropriation Act passed in that session.
