John Tucker Williams (1789 – September 9, 1854) was a British naval officer and political figure in Canada West.

In 1817, when the naval fleets were dispersed, he returned to England, but came back to Upper Canada in 1818, bearing dispatches for a land grant.

[1][2] Williams first settled in Cobourg and later moved to Port Hope (at that time in Durham County), where he built his homestead, Penryn Place.

[6] Originally a moderate Reformer, he consistently supported the Governor General, Lord Sydenham, in the first session of the first provincial Parliament.

Williams was part of a delegation sent to Britain during the debate on the Corn Laws, to represent Canadian agricultural interests.

One of their sons was Arthur Trefusis Heneage Williams, who later represented Durham East in the provincial legislature and federal Parliament.
