Final answer:
The 2018 Physical Activity Guidelines recommend at least 150 minutes of physical activity per week for Canadian adults, but many do not meet this recommendation.
Step-by-step explanation:
The 2018 Physical Activity Guidelines recommend that Canadian adults engage in at least 150 minutes of moderate-intensity aerobic activity per week, or an equivalent combination of moderate- and vigorous-intensity activity. This is the minimum amount of physical activity needed to obtain substantial health benefits.
However, according to a report from the American Heart Association, 8 out of 10 Americans do not meet these guidelines, so it is likely that a similar percentage of Canadian adults also do not engage in the recommended amount of physical activity.
