The main languages of education in Canada are English and French, which are official languages at the Federal level, making it a bilingual nation. Canada generally has 190 school days in a year, officially starting from September to the end of June. The curriculum is designed to elicit the development and quality of people’s cognition through guiding accommodations of individuals to their natural environment and changing social order. Canada does not have a federal department of education or an integrated national system of education. Within the federal system of shared powers, Canada's Constitution Act of 1867 provides that "In and for each province, the legislature may exclusively make laws in relation to Education."
