I think the top cause is the mRNA drugs. I’m sure there have been medical staff getting burnt out and quitting over the past 2 years. I’m sure the Canadian medical system was already strained. That’s not enough to explain these unprecedented emergency room closures across the nation. Most provinces fired all of their vaccine free healthcare workers (Ontario didn’t). Many of the remaining vaccinated ones are either disabled or unable to work the long hours they used to. That could account for a lot of the ones who got “completely burned out”. Combine that with the ongoing surge of vaccinated people ending up in the hospital due to their injuries. The article tries to blame this on COVID-19 hospitalizations, but even those inflated official numbers are not high right now. This is the COVID-19 vaccines.
