The Canadian loss was 9 killed, 37 wounded (some severely enough to require amputation), and 22 died of wounds or disease later. One British soldier, Corporal Carrington, 47th (Lancashire) Regiment of Foot, died on a forced march from Chippawa to Stevensville. O'Neill claimed he had one or two men killed, but Canadians claimed more.

The relatively low casualty figures make this an interesting battle for proponents of theories about soldiers' reluctance to shoot to kill, but could also be accounted for by the fact that the Fenians had deployed only their skirmishers in an attempt to lure the Canadians towards their main force which did not advance until the last minutes of the battle, when they launched the bayonet attack that broke Canadian lines.

Alexander Muir, author of the unofficial Canadian national anthem, "The Maple Leaf Forever", fought with the Queen's Own Rifles of Toronto at Ridgeway, writing the song in 1867, the year after Ridgeway.
