The Act of Union proclamed on February 10, 1841 united the Provinces of Upper and Lower Canada. A revision was soon after begun of the statutes of Upper Canada in force at the date of the union. A commission for that purpose, dated July 25, 1840, was issued to John Beverley Robinson, James B. Macaulay, William Henry Draper, and John Hillyard Cameron, whose names appear in this volume on p. 3. They were directed to examine and revise the statutes passed and enacted by the parliament of Upper Canada and to report upon them. The report to Governor-General Sir Charles Bagot, in which the commissioners announced the completion of the project, is dated March 8,1843, and appears as a preface. In this, as in earlier "revisions", no actual consolidation of the statutes was attempted. The various acts in force were printed as they had been passed, omitting only such portions as had expired or been repealed, with notes stating the reasons for omissions, and giving the provisions, if any, which the Legislature had substituted for repealed clauses. Errors were left uncorrected, except by way of a note directing attention to them; and the revision then replaced preceding volumes of statutes.
