Agricultural producers must comply with a number of laws and regulations. The following list is not exhaustive, but it includes the main regulations that apply to agriculture.
At the federal level, the Pest Management Regulatory Agency is responsible for registering all crop protection products that can be used in Canada. The Pest Control Products

In Quebec, agricultural activities are regulated, among others, by the Agricultural Operations Regulation (AOR) and the Pesticides Management Code. The AOR aims to limit the overfertilization of cultivated land with phosphorus and the potential contamination of bodies of water with fertilizers. It is this regulation that obligates every farming business to produce an annual agro-environmental fertilization plan (AEFP) and phosphorus report (refer to the AEFP section on the website). The requirements for piles in the field; the minimum distances from ditches, water bodies, and wells; and the final dates for spreading certain fertilizers are also outlined in the Act.
