He would soon move west again to what would later become the province of Saskatchewan, where he would continue his business, providing his product to the local police establishments and soldiers during the North-West Rebellion.

In retirement, Gallagher lived on a lavish estate on land he owned atop the Edmonton River Valley until his death in 1932.

When his father relocated to Winnipeg in 1877, he established a wholesale and retail meat distribution business, P. Gallagher and Son, which Cornelius and his brother, Edward would work in.

[1][2] Cornelius Gallagher in 1888 moved to Battleford, North-West Territory (today in Saskatchewan) in 1888, where he bought out his father's firm's interests.

He had been intrigued with the fact that majority of the territory's wheat and vegetable crops came from the Edmonton area, and scenting a business opportunity, decided to settle there.

[1] Purchasing a lot for his business less than 24 hours after arriving in Edmonton, Gallagher established with Calgary based businessman, William Roper Hull, the Gallagher-Hull Meat Company, a wholesale and retail butcher.

Offering a variety of different proteins, such as veal, beef, lamb, turkey, chicken, goose, and pork, the business rose to become the largest of its kind in the developing city of Edmonton, producing over 200,000 pounds (91,000 kg) of meat per year by the turn of the century.

[9] Once this term expired in 1896, Gallagher stayed out of politics for several months until mayor Herbert Charles Wilson resigned over a dispute involving town funds.

[14] During his brief term as mayor, Gallagher oversaw the town during a time when many prospectors headed to the Klondike Gold Rush saw Edmonton as a stopover point.

During this term he sat on committees involved in issues relating to finance, police and utilities (fire, water and light).

The 1912 publication, History of the province of Alberta, states the following: In view of success to which Cornelius Gallagher has attained, it is but just to enter somewhat in detail concerning the plans and methods he has followed and the characteristics which he has manifested in an industrial and commercial career marked by consecutive progress.

His business connections from the beginning continually broadened in their scope and importance and force of character and well developed talents have made in a power in the field of commercial, industrial and financial activity.

Tireless energy, keen perception, honesty of purpose, a genius for devising and executing the right thing at the right time, joined every-day common sense, are his chief characteristics.
