About The Alliance Lawyers

The Alliance Lawyers is a general practice law firm in Owen Sound, Ontario, serving clients across Grey and Bruce Counties. Its roots go back to around 1950, when Harold Van Wyck, who had served in the Second World War, began practicing law and joined William Pattison Telford Jr. Telford had practiced since the early 1900s and represented the area in the Canadian House of Commons. Together they formed Telford and Van Wyck, working out of the Professional Centre on Third Avenue East.

Over the following decades the partnership took on new lawyers, including John Kirby, James L. Van Wyck, John McGibbon, Don Gordon, and Clayton Conlan, and it operated under a series of names as the roster changed. In 2010 the firm formed an alliance with lawyer Brian Barrie and adopted its current name, moving into the Victorian building at 142 10th Street West that it still occupies. Two of its former partners, Don Gordon and Clayton Conlan, later became judges of the Superior Court of Justice.

Today the firm practices business law, civil litigation, labour and employment law, family law, municipal law, real estate and mortgages, and wills and estates. Its four lawyers include partner Jill Sampson, along with Erroll Treslan, Shannon Wallace, and Meghan Hillis.
