Together, they formed the Agricultural Winter Fair Association of Canada and quickly received,[2] in 1920, permission from King George V for use of the prefix royal.

Plans called for the first mounting of the Royal Agricultural Winter Fair to take place in 1921, but this was delayed when a heating system for the new arena could not be installed in time.

The fair then, save for the years when Canada was embroiled in the Second World War, consistently provided for farmers a forum to display equipment, discuss new trends, and showcase wares.

Over 6,000 animals arrive in Toronto each November, including over 4,900 head of cattle, sheep, goats, pigs, rabbits, and fancy bird, and over 900 horses and ponies, plus numerous displays of crops and vegetables, educational exhibits, and feature attractions.

The latter include The Royal Culinary Academy, which provides demonstrations and interactive opportunities for the public, food sampling, along with a wide variety of other education and entertainment features each day and evening.
