Final answer:
The incorrect option regarding agricultural issues Canadians face today is the purported competition due to a high number of farms, as economic pressures have instead led to a decrease in the number of farms.
Step-by-step explanation:
The option that is not an agricultural issue that Canadians are facing today is 'Increasing competition between farmers due to the huge number of farms'. Economic pressures, in fact, have led to a tremendous loss of the number of farms, especially small farms, over recent decades. This contraction of the number of farms contradicts the idea that there is increasing competition due to a large number of farms. Issues that do affect Canadian agriculture include subsidies, loss of farmland due to urban development, and genetic modifications to crops.
