Canada’s COVID-19 cases are still falling after Thanksgiving weekend, data shows This year’s rules are less stringent than in 2020, when Premier François Legault banned all adult Halloween activities and told families they could only trick-or-treat with members of their own households.But despite the improving COVID-19 situation, the government says it’s still important to be careful and for those with symptoms to stay home.“For those who don’t show symptoms and who participate in the gathering and distribution of candy, remember that caution is still in order to limit the risks of spreading the virus,” the Health Department said in a statement.The COVID-19 pandemic prompted some Canadian cities to ban trick-or-treating altogether last.
