Allward's first commission was for the figure of Peace on the Memorial of the Battles in the North-West (1895) in Queen's Park, Toronto. Other early works included a life-sized figure of Dr Oronhyatekha commissioned by the Independent Order of Foresters for the opening of the Temple Building in Toronto (1899), and the Old Soldier, commemorating the War of 1812 in Toronto's Portland Square (now Victoria Memorial Square) (1903). Also in 1903, Alas elected an associate of the Royal Canadian Academy and in 1918 became a full academician. Now well established he received commissions to do busts of Lord Tennyson, Sir Charles Tupper, Sir Wilfrid Laurier and others. On the grounds of Queen's Park are statues of General John Graves Simcoe and Sir Oliver Mowat, completed in 1903 and 1905 respectively.
The art of Walter Allward lives on in numerous substantial monument and designs in Canada and abroad. He was first elected a member of the Royal Canadian Academy of Arts in 1903, and his bronze diploma work of 1920, The Storm, was acquired for the National Gallery of Canada. He is a character in Jane Urquhart's book The Stone Carvers.
