You are going to have to spell out exactly what the Canadian Public Health service is supposedly “hiding” because I don’t see it. I see that they rewrote and rearranged the page, but the information presented is pretty much the same.
Keep in mind that artificially generated aerosols are NOT relevant to the natural course of infection. While droplets can be propelled into the air through some hospital procedures and other activities (such as gathering up soiled wet sheets), that does NOT constitute an airborne mode of transmission. What it DOES mean is that you need complete PPE before engaging in activities that could generate droplets. No one is going to catch Ebola by being on the other side of a room from an Ebola patient because it is not naturally airborne.
