York Region's public transit is also making masks mandatory starting Thursday.
Toronto's top public health official earlier recommended that city council approve a new bylaw that will make it mandatory for residents to wear masks in all "indoor public spaces".
She said that COVID-19 "is unlike any infectious disease we have faced in our lifetime" and while the science on masks is incomplete there is now a "growing body of evidence" that shows they can help prevent the spread of the virus, especially as more parts of the economy reopen.
"It is about public spaces where the general public has free and ready access, to try and limit the risk", de Villa said. "It is about respecting and protecting each other", he said. I can say that's true for me, because I have been wearing a mask regularly in recent times. Those people should try their best to remain physically distanced from others while in public spaces.
Children under two years old and anyone with health conditions that would be affected by wearing a mask will be exempt from the rule.
When will the bylaw take effect?
The bylaw comes into effect on July 7 and will be reviewed on a monthly basis.
What does this mean for schools reopening in early September? They were hoping the province would put in a provincial order, however, Ontario's minister of health has said such a move can be done at the municipal level to ensure regions can be responsive to local needs.
Will there be a fine for not wearing a mask?
"To be candid about it we don't really have the resources to go around and look at every store and look at every person that is in one of those places", he said. "We are going to rely on people by and large to get educated and to do the right thing".
Who else is doing this?
Ford was asked about the pending bylaws during his daily news conference on Tuesday afternoon and he said he was in favour of different regions and municipalities instituting mandatory masks as necessary. There is no specific implementation date, even though at first Patrick Brown's office said the masks will be mandated as of Monday, July 6.
No timeline has been provided for the bylaw in Mississauga or Caledon. The use of masks on the TTC will not be enforced, officials have said.
As well, when asked last week about making masks mandatory across the province, Premier Doug Ford said it would be too hard to enforce, especially in areas in the north that have not had any confirmed cases of COVID-19.
