query: Who was the leader of the Upper Canada Rebellion?
passage: Upper Canada Rebellion
The Upper Canada Central Political Union was organized in 1832-3 by Dr Thomas David Morrison (mayor of Toronto in 1836) while William Lyon Mackenzie was in England. This union collected 19,930 signatures on a petition protesting Mackenzie's unjust expulsion from the House of Assembly by the Family Compact.[5] The Reformers won a majority in the elections held in 1834 for the Legislative Assembly of the 12th Parliament of Upper Canada and Mackenzie was again elected as member for York, but the Family Compact held the majority in the Legislative Council, and the two Houses of government were at loggerheads.

Dr. Rolph, however, had heard that the Lt. Governor had been informed of the plan, and sent a note to Lount moving the march from the north forward to December 4, 1837. When hearing about this change of plans, Mackenzie quickly tried to send a messenger to Lount to tell him not to arrive until December 7. This message was not received in time, with Lount replying that the rebels had already been ordered to march to Toronto and were on their way.[28] Barely armed with pikes and guns for hunting fowl, the farmers from York County marched from Newmarket down Yonge Street towards Toronto and Montgomery's Tavern.
