WATCH | Canada could be seeing the start of a delta-driven 4th wave:Canada could be seeing the start of a delta variant-driven 4th wave 2:05 New Public Health Agency of Canada COVID-19 data shows an uptick that could be the start of a fourth wave, driven by the spread of the delta variant. The latest available federal public health data shows roughly 90 per cent of all COVID-19 cases reported in Canada since the start of the country's vaccination program in mid-December have been among unvaccinated individuals. Almost all public health restrictions in Alberta were lifted on July 1, for instance, and the province plans to scale back isolation requirements, contact tracing and asymptomatic testing next week. Rising vaccination rates, alongside public health measures like mask-wearing, may ward off the worst outcomes of a fourth wave, even as delta spreads.
