The elections of 1825 had a very important influence on the political conditions of the upper province, since they brought into the assembly Peter Perry, Dr. Rolph, and Marshall Spring Bidwell, who became leading actors in the Reform movement which culminated in the concession of responsible government. But the most conspicuous man from 1826 until 1837 was William Lyon Mackenzie, a Scotchman of fair education, who came to Canada in 1820, and eventually embraced journalism as the profession most suited to his controversial temperament. Deeply imbued with a spirit of liberalism in politics, courageous and even defiant in the expression of his opinions, sadly wanting in sound judgment and common sense when his feelings were excited, able to write with vigour, but more inclined to emphatic vituperation than well-reasoned argument, he made himself a force in the politics of the province. In the _Colonial Advocate_, which he established in 1824, he commenced a series of attacks on the government which naturally evoked the resentment of the official class, and culminated in the destruction of his printing office in 1826 by a number of young men, relatives of the principal officials--one of them actually the private secretary of the lieutenant-governor, Sir Peregrine Maitland. Mr. Mackenzie obtained large damages in the courts, and was consequently able to continue the publication of his paper at a time when he was financially embarrassed. The sympathy felt for Mr. Mackenzie brought him into the assembly as member for York during the session of 1829. So obnoxious did he become to the governing class that he was expelled four times from the assembly between 1831 and 1834, and prevented from taking his seat by the orders of the speaker in 1835--practically the fifth expulsion. In 1832 he went to England and presented largely signed petitions asking for a redress of grievances. He appears to have made some impression on English statesmen, and the colonial minister recommended a few reforms to the lieutenant-governor, but they were entirely ignored by the official party. Lord Glenelg also disapproved of the part taken by Attorney-General Boulton--Mr. Robinson being then chief justice--and Solicitor-General Hagerman in the expulsion of Mr. Mackenzie; but they treated the rebuke with contempt and were removed from office for again assisting in the expulsion of Mr. Mackenzie.
