COVID-19. Ontario lifts mask mandate in most settings March 21, all directives to drop by April 27 “As we continue on this path, we are able to take a more balanced and longer-term approach to the province’s pandemic response, including in Ontario schools, by removing many of the measures that have been put in place over the past two years.,” the letter reads.“This does not mean COVID-19 has disappeared.”The MOH says students and staff should continue to self-screen while it also has plans to update the screening tool.It also says it will continue to provide masks for both students and teachers should they wish to continue wearing them while those who are more at risk should be made aware of new anti-viral options.The letter also notes that good hygiene should be promoted and that there are increased cleaning measures in place.The letter from the province describes its prevention and response measures as being “robust”.“There remain circumstances where masking is recommended or required, and it will be important to foster an environment that is kind considerate and inclusive for those who choose to continue to wear a mask,” the letter reads.
