In 1897 he took up a homestead, (Sec. 19 – 11 – 18 w) six miles north of Brandon in the Forrest district where he and his sons farmed for many year. Roderick became very much aware of the problems farmers faced in the marketing of their produce and observed through first hand experience how they were often taken advantage of by the grain trade. He soon became a champion of the farmer’s cause and dedicated his life to that issue as the pioneer of the movement to organize farm people to better express their needs and aspirations. 1903-1916 Roderick became the first provincial secretary-treasurer of the Manitoba Grain Growers Association, which later became the United Farmers of Manitoba. In 1908 he was appointed editor of the Grain Growers Guide, the voice of organized farmers and their provincial associations, which subsequently became The Country Guide.

He continued in that capacity, in addition to his other responsibilities, until 1921. Over the years from 1893 to 1922, Roderick McKenzie, having learned first hand the problems facing the western farmer, fought their cause at every level. He spoke on many occasions across Canada, from the Maritime Provinces to British Columbia, showing farmers how to organize, an encouraging them to seek a fairer pricing and marketing system for their products, spoke on agricultural policy to Sir Wilfred Laurier (Prime Minister) and was often consulted by Sir Robert Borden (Prime Minister) on matters relating to Canadian agriculture.
