Mansewood is an unincorporated community in Halton Hills, Ontario, Canada.[1]
Middle Sixteen Mile Creek flows through the settlement.
The early settlement was part of The Scotch Block, a large agricultural area in Esquesing Township occupied primarily by Scottish immigrants.[2]
A cemetery is located west of the settlement and contains a grave dating to 1815.[3]
Mansewood had a post office from 1877 to 1914.[4]
In 1889, Owen Robertson, a farmer from Mansewood, was noted for the exceptional growth of his Prize Cluster Oats, an experimental variety. Robertson produced 59kg (130lb) of oats from just 1.4kg (03.1lb) of seed.[5]
