The Tories called the meeting for three in the afternoon so that the working class "mechanics" would not be able to attend. The inability of the mechanics to attend was their saving grace, for the meeting ended in a terrible tragedy when the packed gallery overlooking Market Square collapsed, pitching the onlookers into the butcher's stalls below, killing four and injuring dozens. The Tory press immediately placed the blame on Mackenzie, even though he didn't attend. The Toronto mechanics, ironically spared the carnage because of the hour at which the meeting was appointed, did not appear to be swayed by the Tory press. In the October 1834 provincial elections, Mackenzie was overwhelmingly elected in the second riding of York; Sheriff William Jarvis, running in the city of Toronto, lost to reformer James Edward Small by the slim margin of 252 to 260 votes. Toronto was the site of the key events of the Upper Canada Rebellion in 1837, led by Mackenzie.
