COVID-19: Change Your Greeting

To manage the impacts of COVID-19, everyone has a role to play. It takes more than action from the government and health sector to protect the health and safety of Canadians. Each of us can do our part by understanding how the coronavirus spreads and how to prevent illness.
One thing that you can do is change the way you interact with others. Instead of giving a hug or shaking a hand, try a friendly wave instead. Social distancing is also encouraged to help limit the spread of the virus.
