Allan's Mill was a watermill located on both banks of the Speed River in Guelph, Ontario, Canada.

[1][2] The first industrial establishment in Guelph,[3] the original wooden mill was built in 1830 for the Canada Company by Horace Perry, who sited it on the west (right) bank of the Speed River.

[3] Around 1850, the original wooden structure was removed and replaced with one made of limestone, and a bridge was added across the river, connecting the two halves of the mill.

[10] In the 1960s, the site was home to a feed and seed business and a plastics firm, until the buildings were destroyed by fire in 1966.

[4] After a period of brownfield restoration, construction began in 2014 on The Metalworks, a new condominium apartment complex on the site of the old W. C. Wood factory.
