Quebec has had 174,839 confirmed COVID-19 cases and 7,715 deaths since the beginning of the pandemic.
Hamilton will join those regions in the lockdown stage of the province's pandemic plan on Monday.
Ford tweeted "everything is on the table" when it comes to the next steps for the province's COVID-19 response.
"The trends we're seeing throughout Ontario are very, very concerning", Ford said.
The Ontario Hospital Association has called for a "robustly" enforced four-week lockdown for all regions in the "red" zone, or the fourth tier, of the framework-or any public health unit reporting a rate of 40 COVID-19 cases per 100,000 people.
The premier said more details for the rest of the province would be revealed on Monday.
The move doesn't come as a huge surprise, as Ontario Premier Doug Ford had said earlier today that the city would not be coming out of grey zone restrictions after its initial 28-day-long lockdown period expires on Monday.
Ford made the comment as he delivered prepared remarks prior to an emergency meeting via teleconference with 113 Ontario hospital leaders on Friday afternoon.

"However now more than ever we are urging everyone to continue following public health measures and advice, especially over the holiday season".
Tory, who has called for new measures to help flatten the virus curve, did so again Friday.
To date, Ontario has seen 151,257 cases of COVID-19, and 4,098 deaths.
The hospitals in Toronto and Ottawa began administering the shots Monday, and the government said Friday that they have given more than 2,300 doses to health-care workers thus far.
