the Montreal Gazette. In 1907 he founded the Montreal Engineering Company. In 1909, also under the umbrella of his Royal Securities Company, Aitken founded the Calgary Power Company Limited, now the TransAlta Corporation, and oversaw the building of the Horseshoe Falls hydro station. In 1910–1911 Aitken acquired a number of small regional cement plants in Canada, including Sir Sandford Fleming's Western Canada Cement Co. plant at Exshaw, Alberta, and amalgamated them into Canada Cement, eventually controlling four-fifths of the cement production in Canada. Canada was booming economically at the time, and Aitken had close to a monopoly on the material. There were irregularities in the stock transfers leading to the conglomeration of the cement plants, resulting in much criticism of Aitken, as well as accusations of price-gouging and poor management of the cement plants under his company's control. Aitken sold his shares, making a large amount of money. Aitken had made his first visit to Britain in September 1908, and when he returned there in the spring of 1910, in an attempt to raise money to form a steel company, he decided to make the move permanent, but not before he led the underwriting, with a preponderance of British money, of an amalgamation of smaller units into the Steel Company of Canada. Very shortly later Aitken moved his family to the UK.

The two men had a lot in common: they were both sons of the manse from Scottish-Canadian families and both were successful businessmen. Aitken persuaded Bonar Law to support him in standing for the Unionist Party in the December 1910 general election at Ashton-under-Lyne. Aitken was an excellent organiser and, with plenty of money for publicity, he won the seat by 196 votes. Aitken's "bumptious" election campaign brought him some notoriety. Aitken rarely spoke in the House of Commons, but did promise substantial financial support to the Unionist Party, and in 1911 he was knighted by King George V. Aitken's political influence grew when Bonar Law replaced A.J. Balfour as leader of the Unionist party late in 1911. Aitken's demands for a protectionist bloc uniting the British empire made him into a disruptive force in the Conservative and Unionist ranks as the idea of a
