He was the UFO's sometimes controversial general secretary, who was given to making bizarre pronouncements, during the period in which it became a political party and took power in the province following the 1919 provincial election.
Morrison helped found the UFO in 1914 as a farm advocacy organization of which he remained its secretary until 1933, and over which he exercised a sometimes somewhat eccentric leadership style.
Despite his party's winning of enough seats in the Ontario Legislature, Morrison retained reservations about the UFO even forming a government.
Morrison continued as UFO general secretary, yet, having declined to be Premier himself, steadfastly proved through a series of actions and stances to be unwilling to exercise a supportive role during Drury's Premiership.
Morrison objected to initiatives by the Drury government such as a superannuation scheme for civil servants which was denounced by farmers.
The United Farmers of Ontario, as led by Morrison, could sometimes take stances widely regarded as bizarre and irrational.
For example, even when the grouping was the leading element in Ontario's government, Morrison's UFO articulated hostility to the idea of good roads.
After 1923, former Premier Drury, for his part, was left with the legacy of the memory of what may be widely regarded as many, highly unusual happenings during his Premiership.
Morrison's daughter, Rae Luckock, became a politician and served as an Ontario Co-operative Commonwealth Federation Member of Provincial Parliament in the 1940s.
It was equally difficult for Drury to try to govern without Morrison, since the latter as UFO leader had the power to bring him down (which, in substance, did indeed happen).
