It takes many generations for a single country to evolve from its primitive state into what would be considered a "developed" nation. The changes that occur within the country are generally attributed to a small number of visionary individuals. Many people can be credited with contributing to the progress of Canada. John G. Diefenbaker, arguably the most influential person in Canadian history, played a crucial role in the country's development to what it is today. Diefenbaker's work led to the redefinition of Canada's cultural identity, the creation of important bills and policies within government legislation, as well as the development of a position on foreign affairs and many policies addressing global issues. John Diefenbaker was instrumental in introducing the Bill of Rights, which "provides Canadians with certain quasi-constitutional rights in relation to other federal statutes" (wikipedia.com). The Bill of Rights, created in 1960, gave Canadians freedom of speech and freedom of religion, the right to life, liberty and security of the person and, in another section, the right to fundamental justice; these are all things that have been left off the paper. Diefenbaker also made some questionable decisions such as the decision to cancel the Avro Arrow project, which was a Mach-2 interceptor jet. This jet was to be the Interceptor of the Canadian Air Force from 1960 and beyond. The project had been started when the Liberals were in power but in June 1957 the Liberals lost the election to John Diefenbaker and the Conservatives. Diefenbaker thought the project required too much time and money, and in February 1959 he canceled the project. Another policy endorsed by Diefenbaker was the Agriculture Rehabilitation and Development Act, which aimed to improve the vitality of rural communities through better use of resources and retraining to facilitate the exit of marginal farmers into other jobs, as well as empowering the Canadian Wheat Board to make advance payments to producers on a portion of the grain stored on their farm. Diefenbaker also played an important role in obtaining free health care; in 1961, the Royal Commission on Health Services was created, which studied and reported on the health needs of Canadians. The following year, the Government of Saskatchewan offered free access to medical services to all its citizens. Diefenbaker implemented many bills, policies and acts, but was also instrumental in redefining Canada's cultural identity.
