The same year, he moved to Portage la Prairie, Manitoba, where he practised law with his uncle in the firm MacDonald and Hyndman.

During this time, he ran unsuccessfully for the House of Commons of Canada as a Conservative candidate in the riding of Edmonton; he finished second to Liberal Frank Oliver in a two-person race.

He ran for the Legislative Assembly of Alberta in the 1913 provincial election as a Conservative in Sturgeon, but was defeated by Liberal John R. Boyle (himself a former Edmonton alderman).

From 1940 until 1942 he served as Wartime Rental and Salaries Controller, in which capacity he heard appeals by German and Italian prisoners in Canada and supervised the Excess Profits Tax Act.

His grandson, Lou Hyndman, served as a Progressive Conservative member of the Legislative Assembly of Alberta (representing Edmonton West from 1967 until 1971 and Edmonton-Glenora from 1971 until 1986) and provincial treasurer.
