N.B. doctor warns about COVID-19 hospital capacity as students head back to school Green Party Leader David Coon says action is needed quickly.“I would like to see some of the public health measures reinstated, particularly masking in public spaces indoors and an extension of vaccine mandates for congregate settings where you’ve got large numbers of people in enclosed spaces,” he tells Global News.Coon also wants people who are unvaccinated and visiting from outside the regional bubble to have to undergo self-isolation upon arrival in New Brunswick.People’s Alliance Leader Kris Austin says while he’d be open to some form of incentive for people to get vaccinated, he wouldn’t support a mask mandate and another state of emergency at this.
