Health-care workers who have already received their first dose will still get a second, but the province said that shot may be delayed by up to 42 days depending on supply.
These adjustments are being made following notification by the federal government of reductions in Pfizer-BioNTech vaccine shipments.
Ontario Premier Doug Ford says he's hoping by the summer that anyone who wants a COVID-19 vaccine will be able to get a vaccine.
On Jan. 19, the federal government notified the province of further reductions in Pfizer-BioNTech vaccine shipments.
In a press release announcing the change, the Ontario government said they had missed this week's Pfizer vaccine dose deliveries and were expecting "just over 26,000 doses" for the first weeks of February.
The province is still planning to administer first doses to residents in all long-term care homes across the province by Feb. 5, depending on delivery dates of the vaccine in the first week of February.
"Until vaccines are widely available, we are urging all Ontarians to continue to follow all public health advice", the provincial leadership said.
The Canadian Rangers are members of the military that live and work in remote regions, and many members of the group are residents in the First Nations themselves.
Ornge will also be moving forward with Operation Remote Immunity in February when it will be vaccinating residents in 31 fly-in communities across Northwestern Ontario.
"Staying the course will also buy critical time for vaccines to begin working, as we continue to prepare the way for widespread and lasting control of COVID-19 through safe and effective vaccines", Tam added.
The province will provide an update on the COVID-19 vaccination plan at Queen's Park Monday afternoon. "We have the capacity to vaccinate almost 40,000 people per day and we are working to triple that capacity pending federal government supply".
Health Minister Christine Elliott says 727 of the new cases are in Toronto, 365 in Peel Region, and 157 in York Region.
Ontario was one of the first provinces to declare a state of emergency, and within weeks, the government established a provincial laboratory network among public health, hospital and community labs to create "unprecedented testing capacity".
A rapid COVID-19 test developed by an Ottawa company, which delivers a result in less than an hour, was approved by Health Canada on Saturday.
That means other groups deemed not as high-risk, including long-term care staff and essential caregivers, will have to wait longer to be vaccinated.
While Kingston and the Islands will receive $1.07 million, the remaining $739,000 of Monday's $1.8-million announcement will go to six long-term care homes in Hastings-Lennox and Addington. These intervals are aligned with guidance provided by the National Advisory Committee on Immunization (NACI).
