The Canadians ‘know’ differently than the CDC:
MODE OF TRANSMISSION: In an outbreak, it is hypothesized that the first patient becomes infected as a result of contact with an infected animal. Person-to-person transmission occurs via close personal contact with an infected individual or their body fluids during the late stages of infection or after death. Nosocomial infections can occur through contact with infected body fluids for example due to the reuse of unsterilized syringes, needles, or other medical equipment contaminated with these fluids. Humans may be infected by handling sick or dead non-human primates and are also at risk when handling the bodies of deceased humans in preparation for funerals.
In laboratory settings, non-human primates exposed to aerosolized ebolavirus from pigs have become infected, however, airborne transmission has not been demonstrated between non-human primates. Viral shedding has been observed in nasopharyngeal secretions and rectal swabs of pigs following experimental inoculation.

Being a nit-picker, I have to correct this.
The pigs did not pass aerosolized Ebola virus to the monkeys. Pigs sneeze a lot because they do get a respiratory infection with Ebola. Sneezes contain enough large droplets that virus can be present in the droplets. The pigs were separated from the monkeys by 20 cm, which is less than a foot--they could certainly get close enough to sneeze directly on the monkeys. Plus, the pigs could also kick debris--which probably contained wet snot because they had runny noses--from their pen into the monkey cage. This experiment did NOT demonstrate aerosol transmission. Aerosols are small particles that dry quickly and travel a distance--Ebola is large, and is destroyed by drying.
I honestly do not know why people are so fixated by this idea that Ebola MUST be airborne, or that it is about to become airborne. Besides being physically almost impossible, the virus has no reason to become airborne since it infects and transmits just fine the way it is. I'm guessing that the fixation on airborne transmission is cultural memory--a remnant of the predominant belief that bad air causes diseases, which existed before we knew anything about germs and apparently still exists in some form.
