The term "food system" is used frequently in discussions about nutrition, food, health, community economic development and agriculture. A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, and disposal of food and food-related items. It also includes the inputs needed and outputs generated at each of these steps. A food system operates within and is influenced by social, political, economic and environmental contexts. It also requires human resources that provide labor, research and education. Food systems are either conventional or alternative according to their model of food lifespan from origin to plate.

Conventional food systems operate on the economies of scale. These food systems are geared towards a production model that requires maximizing efficiency in order to lower consumer costs and increase overall production, and they utilize economic models such vertical integration, economic specialization, and global trade.

First Nations is a term that collectively refers to various Aboriginal peoples in Canada who are neither Inuit nor Métis. There are currently over 630 recognized First Nations governments or bands spread across Canada, roughly half of which are in the provinces of Ontario and British Columbia. The total population is nearly 700,000 people. Under the Employment Equity Act, First Nations are a "designated group", along with women, visible minorities, and persons with physical or mental disabilities. They are not defined as a visible minority under the Act or by the criteria of Statistics Canada.

The term First Nations (most often used in the plural) has come into general use for the indigenous peoples of the Americas located in what is now Canada, except for the Arctic-situated Inuit, and peoples of mixed European-First Nations ancestry called Métis. The singular, commonly used on culturally politicized reserves, is the term First Nations person (when gender-specific, First Nations man or First Nations woman). A more recent trend is for members of various nations to refer to themselves by their tribal or national identity only, e.g., "I'm Haida," or "We're Kwantlens," in recognition of the distinctiveness of First Nations ethnicities.
