Today's Ottawa update

Ottawa Public Health (OPH) reported 62 more COVID-19 cases and one death on Sunday. The last time health officials reported a death in the nation's capital was Sept. 10.

The city is up to 498 known active cases, one of the many indicators that are close to what Ottawa saw in June 2021 at the end of the pandemic's third wave.

Ottawa's Medical Officer of Health, Dr. Vera Etches, has asked people to "approach September with caution" given the more infectious delta variant that's behind the fourth pandemic wave.

While COVID-19 cases have steadily trended upward, several health experts say they don't expect schools to shut down during the fourth wave.
