During his sojourn in Chicago Mr. Angus became acquainted with the spirit of the great west and what it was hoped might be accomplished there. He saw the states of Illinois and Iowa budding forth from prairie to splendidly developed communities and reasoning by analogy he recognized what the future had in store for the Canadian west following the construction of the Canadian Pacific Railway. The splendid financial standing of the Canadian Pacific Railway Company today is also in a measure due to the wisdom of this man, whom no doubt Sir Thomas Shaughnessy considers one of his wisest counsellors. In 1864 Mr. Angus returned to Montreal to become second assistant manager of the Bank of Montreal, was later appointed assistant manager and became manager in 1868. In 1869, or two years after the union of the British North American colonies, Mr. Angus was appointed general manager of the Bank of Montreal, a position which he held until November 1, 1879. It is said that during these ten years his advice was sought many times by the different finance ministers of the Dominion not only as regards federal loans but also concerning the general financial policy of the country. Although a native of Scotland, where free trade exists, Mr. Angus looked with favor upon the protectionist program, which triumphed in Canada on the 18th of September, 1878. He saw therein a means whereby the Dominion could become a great manufacturing country, and he has lived long enough to see the splendid fruition of that policy.
