SAINT JOHN, N.B. -- Change has been swift for areas of New Brunswick under the red level of COVID-19 restrictions, but it hasn't been as dramatic as last spring's shutdown. The Moncton region (Zone 1), Saint John region (Zone 2) and Fredericton region (Zone 3) went back to red on Wednesday, with the Edmundston region (Zone 4) going back on Monday. Gyms, recreational facilities, spas, salons and entertainment venues must close under the red category. In addition, churches can only hold drive-in services, and restaurants can only provide take-out and delivery options. Other so-called non-essential retailers, which were shut down under March's restrictions, are able to remain open under the province's current red level. Schools in the red zone are also staying open, with modifications and temporary closures being enforced in school buildings with confirmed COVID-19 cases.
