About Mackenzie Chapman Hilliard

Mackenzie Chapman Hilliard is a small general-practice law firm in Acton, a community within the town of Halton Hills, Ontario. Operating as barristers and solicitors from an office on Main Street South in the town's historic downtown, the firm has served the area for over forty years. Its work centers on real estate transactions, wills and estates, business law, and family law, with notary public and commissioner of oaths services offered on a drop-in basis.

Margaret J. Chapman, who was born and raised in Acton, graduated from Osgoode Hall Law School in 1973 and began practicing law in the town soon after, alongside the late Gordon Chapman. Chapman's work has centered on estate planning, estate administration, and real estate transactions, and Chapman is mostly retired but still happy to lend Chapman's expertise. Mark D. M. Hilliard, who grew up in Markham, joined the firm in 2014 after graduating from Osgoode Hall Law School the year before; Hilliard's practice spans real estate, estate planning, family law, and business law. Licensed paralegal Jessica Markou represents clients in Small Claims Court and in landlord and tenant, debt collection, and employment matters.
