He is by birth and early training an Irishman, and was born in the county of Tyrone, on the 24th of December, 1811. His father, the late Mr. William McMaster, was a linen merchant whose resources were not abundant, but who was able to give his son a good education. The latter received his educational training at an excellent private school taught by a Mr. Halcro, who had a high local reputation as a teacher. After leaving school he was for a short time a clerk in a local mercantile house. His prospects in Ireland, however, were not commensurate with his ambition. In 1833, when he was in his twenty-second year, he resigned his situation, and emigrated. Upon reaching New York he was advised by the resident British Consul not to settle in the United States, but to make his way to Canada. He acted upon the advice, and passed on to Toronto--or, as it was then called, Little York. The conditions of the wholesale trade in Canada in those days were very different from those which now prevail. The preeminence of Montreal as a point of distribution for both the Provinces was well established, and the wholesale trade of Little York was comparatively insignificant. There were very few exclusively wholesale establishments in the Upper Canadian capital, but several of the largest firms contrived to combine a wholesale and retail business. Young William McMaster, immediately upon his arrival at Little York, obtained a clerkship in one of these, viz., that of Mr. Robert Cathcart, a merchant who then occupied premises on the south side of King Street, opposite Toronto Street. After remaining in this establishment somewhat more than a year in the capacity of a clerk, young McMaster was admitted to a partnership in the business, a large share of which from that time forward came under his own personal management. The partnership lasted about ten years, when--in 1844--Mr. McMaster withdrew from it, and started a separate wholesale dry-goods business on his own account, in a store situated on the west side of Yonge Street, a short distance below the intersection of that thoroughfare with King Street. By this time the conditions of trade had undergone some modification. Montreal still had the lion's share of the wholesale trade, but Toronto and Hamilton had also become known as distributing centres, and both those towns contained some large wholesale warehouses. Mr. McMaster's business was a large one from the beginning, but it rapidly expanded, until there was not a town, and scarcely a village in Canada West, which did not largely depend upon the house of William McMaster for its dry-goods supplies. The attempt to make Toronto, instead of Montreal, the wholesale emporium for Western Canada was not initiated by Mr. McMaster, but it was ably seconded by him, and no merchant now living did so much to divert the wholesale trade to western channels. In process of time he admitted his nephews (who now compose the firm of Messrs. A. R. McMaster & Brother) into
