Ill health (probably a stroke) forced him to resign after only two years, and he retired to Nottinghamshire in England. However, his brief tenure was remembered as a period of calm before the coming storm (see Rebellions of 1837).
The city of Sherbrooke, Quebec is named after him, as is a major street in Montreal.
Sherbrooke was unable to persuade the provincial assembly, dominated by dissenters, to make provision for the Church of England even when he offered, as an incentive to generosity, a suspension of the threatened collection of quitrents owed on land grants.
Sherbrooke was determined from the outset not to become embroiled in partisan politics but to steer a neutral, conciliatory course with the aid of personal suasion and fair dealing.
Sherbrooke arranged for the speakers salary of £1,000 a year, originally granted for the duration of the war, to be made permanent, and he purchased the concurrence of the Legislative Council by paying Sewell the same stipend as speaker of the upper house.
Today Sherbrooke Village represents a typical Nova Scotia village from 1860 to pre World War I. With approximately 80 buildings and over 25 of those open to the public, Sherbrooke Village is the largest Nova Scotia Museum site.
Sherbrooke Village reflects Nova Scotia, as it was during the industrial boom in the late 1800's and early 1900's when the economy was built on shipbuilding, lumbering and gold mining.
By 1815, the settlement became known as Sherbrooke, in honour of Sir JohnCoapeSherbrooke, Lieutenant Governor of Nova Scotia.
