    1. @Gary Bandwagon Fallacy combined with selection bias. Just because random YouTube commenters motivated by willful ignorance believe one thing does not make it true, in this case, because they disregard actual research in favour of baseless assertions. Also, your argument from popularity is flawed on its own merit as the like/dislike ratio favours the news.

    1. Cool Vibes you’re literally begging please because you’ll do whatever they tell you to do even if it’s a lie. Canada is pathetic.

    2. Frank Dobson : right! And our neighbour to the south is doing everything right,and that is why they are getting 50,000 plus new cases, and over 750 deaths daily, and still are in the first wave. Use your brain, and not your political rhetoric. It’s a health issue, not a political one.

      Stay safe, stay sane, be well

    3. This is covered in some of the papers I studied. There is transmission via the ocular route, but it’s very small. Transmission in the general public is predominantly determined by respiratory transmission.

  1. The news is just creating fear at this point.
    “wear a mask to save your life”!!!
    “most masks won’t save your life”!!!!
    “Trudeau’s in charge”

    1. @Bryan Johnstone Canadians don’t have republicans. Our form of conservative is way left of Republican.

    2. @First Thoughts Your supposed too argue the point being made, nit picking isn’t productive.
      Point was both Canadian wings are saying similar messages about the virus. Now if you want to hate Trudeau, losing a finance minister in an economic crisis is far better ammo.

    1. I do lots of things moistly. I mostly do my shopping moistly, as well as cutting the lawn moistly. It’s all moist. THEY ALL FLOAT MOISTLY DOWN HERE, HAHAHAHAHAAAAAA.

  2. I wore n95 masks they don’t even work on concrete dust but my employers love to lie worse than turdheds govt who think of can stop a molucule sized covid germ when the facts prove otherwise.

    1. Did you compare the amount of concrete dust on your mouth and nose, with and without the mask? Was that subject to statistical analysis? If no, then your story is just that, an anecdote, and policy cannot be based off anecdotes.

    1. That’s the problem with idiots like you, your reading comprehension and ability to understand what you’re listening to, is equal to that of a goat.

  3. Very disturbing that the hospitals give family of deceased an option to report death as covid related when it has not been the case.
    Absolutely frightening.b

  4. Buy a stormtrooper helmet. Better protection than a mask any day and you get total anonymity as a bonus.

  5. There are several human rights lawsuits in play over this supposed MANDATORY mask rule as it violates several sections of the Charter and many involved in law(including myself) thinks that several questions are utterly valid.

    One person was raped whilst having their mouth covered. As a result, they are being forced to relive the trauma everytime they have to buy groceries…to live.

    This mask wearing is, in a word; nonsense.

    A virus with a fatality rate of .01% is NOT an existential threat.

    .01% of the entire global population.

    .01%.

    8,000,000,000.

    8,000,000,000.

  6. Oh come on guys, when will you ever get the chance again to regularly dress like a ninja in public?
