As people prepare for the Christmas celebrations, public health officials are urging them to avoid gathering with their extended family in person to stop the spread of COVID-19. In Lambton, officials say much of the spread has been at gathering like meat raffles, dart leagues, and workplace social gatherings.
And while people prepare for a quieter holiday, businesses prepare for another 28 day lockdown. The province is shutting down much of the province starting Boxing Day to try to get a grip on the growing number of COVID-19 cases across Ontario.
