After the war, George took law classes at
Osgoode Hall in
York, Upper Canada. He was called to the
Bar of Upper Canada in 1816 and moved to
Dundas, bringing his mother to live with him. At that time, he was the second-largest landowner of the town. His family's connection to a prominent government official named
Thomas Talbot allowed him to be appointed to the roles of clerk of the peace (the first person appointed to this position), registrar of the surrogate court, and clerk of the court for Gore county in 1816. Rolph practiced law throughout the
Hamilton and
Ancaster region. In 1823, Rolph was appointed as captain of the 1st Regiment Gore militia. Rolph did not associate himself with members of the region's aristocratic elite, refusing to attend galas or give toasts at public dinners. This caused the elite to become hostile towards Rolph as he did not use his position to support their causes. Rolph gave asylum to a woman named Mrs. Evans, who was fleeing her abusive husband. Rumours spread that Rolph was committing adultery with Evans, even though Evans was living in a different part of the house. In June 1826 a group of men invaded his home at night, dragged him outside, and
tarred and feathered him. Six were accused of being in the mob during the incident:
George Gurnett, Titus Simons, James Hamilton, Alexander Robertson,
Allan MacNab, and Alexander Chewett. His brother, John Rolph, agreed to represent George in a trial against the assailants. John suggested that they wait before laying charges, and the accused bragged to members of the community about being the assailants. Rolph used this information to begin a civic action against the assailants in August 1827, suing for £1000 each. At the trial, the defence stated that the crime was intended to inform George Rolph of the community's opinion on his supposed adultery with Evans. The jury's verdict was for Simons and Hamilton to pay £20 each in damages. ==Political career==
