The Council for the Affairs of the Province of Quebec, more commonly called the Legislative Council of Quebec (but not to be confused with the later institution with that same name), was an advisory body constituted by section XII of the Quebec Act of 1774. Together with the representative of the Crown (the Governor, Lieutenant-Governor or the temporary Administrator of the province), it acted, between 1774 and 1791, as the legislature of the old Province of Quebec.
The Council had the "Power and Authority to make Ordinances for the Peace, Welfare, and good Government, of the said Province, with the Consent of his Majesty's Governor, or, in his Absence, of the Lieutenant-governor, or Commander in Chief for the Time being.", excepting the power to "lay any Taxes or Duties within the said Province, such Rates and Taxes only excepted as the Inhabitants of any Town or District within the said Province may be authorized by the said Council to assess, levy, and apply, within the said Town or District. for the Purpose of making Roads, erecting and repairing publick Buildings, or for any other Purpose respecting the local Convenience and economy of such Town or District."
Section VII of the Quebec Act opened the door of all provincial offices to Roman Catholic subjects. The section exempted Catholics from taking the Test Oath (the abjuration of the Catholic faith) and made them take an alternative oath of allegiance to the British Crown:
I, A.B., do sincerely promise and swear: That I will be faithful, and bear true Allegiance to his Majesty King George, and him will defend to the utmost of my Power, against all traitorous Conspiracies, and Attempts whatsoever, which shall be made against his Person, Crown, and Dignity; and I will do my utmost Endeavor to disclose and make known to his Majesty, his Heirs and Successors, all Treasons, and traitorous Conspiracies, and Attempts, which I shall know to be against him, or any of them; and all this I do swear without any Equivocation, mental Evasion, or secret Reservation, and renouncing all Pardons and Dispensations from any Power or Person whomsoever to the contrary. So help me GOD.
