LONDON, ONT -- Ontario Premier Doug Ford unveiled Tuesday details of a new five-tiered system for imposing lockdowns and restrictions, and currently London-Middlesex is in the green.

The five levels are Prevent (Green), Protect (Yellow), Restrict (Orange), Control (Red), and Lockdown.

The majority of public health units across the province are in the Prevent stage.

In the immediate region, only Brant County is at the Protect Level.

There are five regions in the Restrict level including Eastern Ontario Health Unit, Ottawa Public Health, Peel Public Health, Toronto Public Health, and York Region Public Health.

The new system will be implemented on Nov. 7, with Toronto’s designation being delayed until Nov. 14.

"It's clear COVID-19 will be with us for a while, which is why we are putting in place a framework that will protect the health and safety of individuals and families, while avoiding broader closures across the province," said Ford.

The framework is designed as an early warning system allowing to scale up and scale back public health restrictions on a regional or community basis, according to Ford.

“By introducing public health measures sooner, we can keep this deadly virus at bay, bend the curve and reclaim a little more of our normal lives," said Ford.

Decisions on moving public health unit regions into the framework will be made by the government based on updated data and in consultation with the Chief Medical Officer of Health, local medical officers of health and other health experts, and will be reviewed weekly.

Here's what is included in each of the five new categories that will be implemented in Ontario:

Green-Prevent

In this category, the region must focus on education and awareness about public health safety measures. Restrictions reflect those of Stage 3, until there is a widely available vaccine or treatment. Highest risk settings remain closed.

To be assigned this status, the health unit must have a weekly incidence rate of fewer than 10 cases per 100,000 people. The test positivity rate must be under one per cent.

Yellow-Protect

In this category, the region will enhance targeted enforcement, fines and education to limit further transmission.

Additional public health measures are required in high-risk settings, such as restaurants, gyms and movie theatres.

Regions placed in the protect category will have a weekly incidence rate between 10 and 39.9 cases per 100,000 people. The test positivity rate must be between one and 2.5 per cent.

Orange-Restrict

When a region moves to this level, enhanced measure and restrictions are applied to slow the spread.

The weekly incidence rate in these regions must be between 40 and 99.9 cases per 100,000 people. The test positivity rate must be between 2.5 and 9.9 per cent.

At this level, hospital and ICU occupancy are increasing.

Red-Control

In the control phase, regions will implement broader-scale measures and restrictions across multiple sectors. This phase will be similar to a modified Stage 2.

The restrictions in this phase are the most severe before moving to a lockdown.

The weekly incident rate is more than 100 cases per 100,000 people. The positivity rate must increase above 10 per cent.

In this stage, hospital and ICU capacity are at risk of being overwhelmed.

Lockdown (Maximum measures)

If trends continue to worsen after measures from the control level are implemented, the region will move to a full lockdown. This means closing all non-essential businesses and reverting to Stage 1 or pre-Stage 1.
