I would listen to the WHO before I listened to any Canadian public health statement. After Canadian public health officials lied to us about the West Nile virus last year I don't believe anything they say. They were telling us last year that West Nile was just like a bad flu and only risky for old people. Now we find out that they were concealing the fact that about 20% of all people who contract West Nile end up with neurological disorders which cause paralysis and can put you into a vegetative state. So don't trust them when they say everything is ok and remember that they don't want to cause a panic so they will conceal the truth to avoid any panic.
BTW, a neighbour of mine is a driver for the TTC and he told me that the TTC is not letting any of it's workers wear masks to protect themselves from SARS. Apparently that's not the message they want to send to the community
