Like during the First World War, many Canadians worked to produce food for the war effort during the Second World War. There were several food production initiatives throughout the war years; this post focuses on the students engaged in Farm Service. Male and female students worked on farms in the summer as a means of gaining course credit while also assisting with food production. Not only did this program help provide food for soldiers fighting overseas, it also instilled democratic values in Canadian youth. The 1941 Labour Gazette stated that:
Some teachers have questioned the advisability of allowing students to leave school so early in the year because of the loss in education. On the other hand this plan may be a gain for education if there is taken into consideration the value of training in Democracy involved in the self-discipline of farm work, the understanding of urban-rural relationships secured, the responsibility of the individual to the community which is developed in rendering a fair day's work for a fair day's pay, the co-ordination of body, mind and spirit in serving the social purpose of food production, and the realization of the value of time, work and money. 
Others, like the Chairman of the Toronto Board of Education, echoed this sentiment when he stated, "in these troubled days, may the boys and girls in our own schools learn the lessons of true patriotism and thus prepare themselves to champion loyalty, fair play and truth." A 1941 government issued handbook (shown below) states that, "this challenge [of Farm Service] is a call to you to take your place in this line of defence and man it so effectively that Great Britain and her allies- fighting for life, liberty and freedom, ours as much as theirs, need never fear a shortage of food." 
In the war's closing years, approximately 35,000 Ontario students were enrolled in Farm Service and stationed on sixty farms across the province. This number included members of Canadian Girls in Training, whose summer program was combined with the Farmerettes. More young women than men were engaged in this service, which was partly attributable to the men fighting on the front, as well as men's tendencies to seek more lucrative summer employment elsewhere in the expanding wartime economy.
