According to guidance released Monday morning, Chief Medical Officer of Health Dr. David Williams says the risk of transmission in those areas is too great.
While Dr. Theresa Tam hasn't ruled out trick-or-treating this year-she suggested trick-or-treating outdoors while practicing physical distancing should be fine-it's unlikely many parents will partake in the annual tradition, especially given the fact Ontario has relegated certain regions to a modified Stage 2 due to a spike in COVID-19 cases.
Here's how it works: The robotic Trick-or-Treat Door will roam around your neighborhood via remote control and stop at different houses.
The province is reporting 704 new cases of COVID-19 today, with 244 new cases in Toronto, 168 in Peel, 103 in York Region, and 51 in Ottawa.
Both trick-or-treaters and people handing out candy should wear a face covering.
There should be no trick-or-treating inside, hands should be washed repeatedly, don't linger on doorsteps, and travel only with your household members.
Williams said that children can still dress up and participate in virtual activities and parties, organize a Halloween candy hunt with people living in their own household, carve pumpkins, have a movie night, share scary stories, or decorate their front lawn.
"A costume mask is not a substitute for a face covering and should not be worn over a face covering as it may make it hard to breathe", officials clarified.
The provincial government is recommending that kids not go out trick-or-treating in parts of Ontario that have been hardest hit by a resurgence in COVID-19 cases.
Williams is also recommending that you check with your local municipality or public health unit for any additional advice or restrictions that may be in place.
"I would also like to remind everyone that we are in a second wave of COVID-19", Williams said in his statement.
