Absolutely NOTHING is clear from that survey due to the methodology in which it was conducted and the questions posed.

It is impossible to even calculate the statistical margin of error from this survey because it is guaranteed to suffer from "sampling bias".  Put very simply the only people who are likely to have answered the survey are those who are passionate about the issue one way or another.  That means it is all but guaranteed to not be a representative sample of Canadians.

Given that the survey is all but guaranteed not to be representative, what is the point in analyzing the results?  All they'll do is give you incorrect data from which you can draw erroneous conclusions.
