January – The King announces that he will not make the Legislative Council an elected body, as it would be inconsistent with the monarchy, but that he will favor measures for the Council's independence.
January – Thomas Spring Rice, the Secretary of State for War and the Colonies writes "If coming events should constrain the British Legislature to interpose its supreme authority to appease the internal dissensions of the Colony, it would then, indeed, become my duty to submit for the consideration of Parliament, some modifications of the charters of the Canadas, not however, for introducing institutions inconsistent with monarchy, but to preserve and cement their connection with the Mother Country, adhering ever to the spirit of the British Constitution, and confining within their legitimate bounds the rights and privileges of His Majesty's subjects."
February 17 – The Ninety-Two Resolutions are passed by the Legislative Assembly of Lower Canada. The complaints relate, chiefly, to nominations of Councillors, partiality in filling offices, of which 47 are alleged to have been distributed among 525,000 Frenchmen, against 157 higher positions, among 75,000 of British origin.
Speaking in the House upon the Ninety-Two Resolutions, which he frames and Mr. Bedard moves, Louis-Joseph Papineau says "It is certain that, before long, the whole of America will be republicanized. If a change be necessary in our present constitution, it is to be undertaken in view of such a conjuncture as I have just mentioned. Would it be a crime, were I to demand that it should? The members of the House are all answerable to their constituents for whatever decisions they may come to, in this regard. And, even though the soldiery should slaughter them for it, they ought not to hesitate, for one moment, to pronounce for any change which they consider beneficial to their country."
Mr. Neilson replies: "The American revolutionists and the British Liberals contended for the maintenance of franchises already acquired; we oppositionists are reaching out our hands for freedom which we never possessed. The Resolutions can not be justified, for they favor the refusal of supplies, without which there would be no means of defraying the expense of governing the Province."
