1805-1832
In January 1805, the estate of Simon McTavish leased the seigneury of Terrebonne for a period of 12 years to Henry Mackenzie (1781- 1832), an agent of the seigneury since 1803. Mackenzie then joined forces with McTavish's former partners, his brother Roderick Mackenzie (c. 1761-1844) and the lawyer turned merchant, Jacob Oldham (c. 1768-1824), to form a company that would evolve under the name Mackenzie, Oldham and Co. l’Île-des-Moulins had become a pre-industrial complex in Terrebonne managed by MacKenzie, Oldham, and Co., and equipped with a forge, a bakery, and various types of mills. The mills produced goods for sale but were also used by the citizens of Terrebonne to grind their flour and cut their wood. In 1832, the seigneury was put up for auction and was bought by Joseph Masson, a wealthy Montreal merchant.
