Slavery in Upper Canada continued until the Imperial Act of 1833[34] but there does not seem to be any record of sales after 1806. Probably the last slaves to become free were two who are mentioned by the late Sir Adam Wilson, Chief Justice successively of the Courts of Common Pleas and Queen's Bench at Toronto. These were "two young slaves, Hank and Sukey whom he met at the residence of Mrs. O'Reilly, mother of the venerable Miles O'Reilly, Q. C., in Halton County about 1830. They took freedom under the Act of 1833 and were perhaps the last slaves in the province."[35] In the Detroit neighborhood there were undoubtedly many slaves, Panis and Negro: most of these were lost to the province on the delivery up of the retained territory in 1796 under the provisions of Jay's Treaty. But some were on the Canadian side and some were brought over by their masters on the surrender. Colonel Matthew Elliott who settled in 1784 just below Amherstburg brought many slaves, some sixty it is said. The remains of slave quarters are still in existence on the place. Jacques Duperon Baby the well-known fur-trader had at least thirty. Antoine Louis Descompte dit Labadie, who raised a family of thirty-three children was the owner of slaves also. He was a wealthy farmer of the Township of Sandwich (now Walkerville) and died in 1806, aged 62. On May 26, 1806, he made at Sandwich his will by which he made the following bequest: "I also give and bequeath to my wife the use or service of two slaves that she may select, as long as she continues to be my widow." After a number of bequests there follows: "I will that all my personal property not here above bequeathed as well as my slaves with the exception of the two left to my wife, be portioned out or sold, and that the proceeds arising therefrom be equally divided between my said wife and the nine children[36] born out of my marriage with her." Some of these slaves were probably Panis. There is extant a parchment receipt dated at Detroit, October 10, 1775, which reads: "Je certifie avoir vendu et livre au Sieur Labadie, une esclave Paniese[37] nommee Mannon pour et en consideration de la quantite de quatre-vingt minots[38] de Ble de froment qu'il doit me payer a mesure qu'il aura au printemps prochain, donne sous ma main au Detroit ce dixieme jour d'Octobre, 1775.
