WATCH: Children not allowed to ‘sing or shout for treats’ this Halloween: Ontario CMOH

"I just wanted to ask about Halloween to start. I noticed that one of the bullet points in the guidance is for kids not to sing or shout for their treats when trick or treating, just curious how you envision that going, kids generally go to the doors and shout tick or treat so they just not be speaking at all," reporter Alison Jones asked Ontario's Chief Medical Officer of Health Dr. Kieran Moore.

"They'll have masks on, it's just not to yell too exuberantly. I think the purpose of that comment was not to aerosolize, and it's just a risk reduction strategy," Moore responded.

"Clearly you have to make your presence known to get your treat, and you have to be able to knock as well as ask for the treat, we just ask not with a high volume that could potentially aerosolize. It's an abundance of caution," Moore continued.

"And last year when Halloween was present in Kingston, and I was giving out candies, kids were great and the event went smoothly without any issues, and the children were all reasonable and lined up appropriately. So I certainly hope across Ontario it goes well again this year," he added.

In Ontario's guidance for celebrating Halloween during the pandemic, they urge families to trick or treat outdoors as much as possible.

"Be creative and build the face covering into your costume. Remember that a costume mask is not a substitute for a face covering. A costume mask should not be worn over a non-medical mask or face covering because it can be dangerous if the costume mask makes it hard to breathe," the guidance states.

The guidance also tells people not to crowd at doorsteps, keep interactions brief, and to use hand sanitizer often.

For those giving out treats, the guidance urged people not to ask "trick-or-treaters to sing or shout for their treats," and to give out only purchased or prepackaged treats.
