Canada's largest province says it's in the third wave -- and officials worry the vaccine rollout may not happen fast enough

Canada's largest province declared Monday it was at the beginning of a third wave of the coronavirus pandemic, pointing to evidence of increasing case counts, hospitalizations and the spread of variants.

"We're in the third wave. The numbers are slowly going up, they're not going as fast as predicted by the modelers," said Dr. David Williams, the chief medical officer for Ontario. He added, "We're now starting to see impacts on our hospital rates, our ICU admissions are up again, our hospital admissions are up again." It was sobering news for a province where the majority of residents have been in some state of lockdown since late last year.
