I thought that Todd's article was a very good summary and discussion of the survey. He has a very clear bias against Gretta (and, apparently thinks little of Eastern Canadian media - which, in all honesty, I have some sympathy with on this issue, given their over-hyping of the Gretta situation), as evidenced by these words, which to me seem dismissive of both Gretta and the Eastern Canadian media:
Douglas Todd said:
I suspect this kind of reality-check won’t stop a lot of Eastern Canadian journalists (predominantly from the otherwise useful CBC) from continuing to gift Vosper a great deal of pseudo-controversial attention, which will in turn help her sell her pro-atheistic books.
So there's clear bias in the article, but a decent discussion of the survey.
As for the Vancouver Sun and Sun Media - well, it's complicated.
The Vancouver Sun is more than 100 years old, so it long predates Sun Media. It's currently published by the Pacific Newspaper Group. The Pacific Newspaper Group is owned by Post Media - who are best known for publishing the National Post (a conservative newspaper that I nevertheless rather enjoy reading - I find it conservative, but generally fair and balanced; a decent perspective. Not long ago (last year I think) Post Media acquired Sun Media, although they haven't merged any newspapers. So the Vancouver Sun is related to Sun Media - sort of corporate cousins, I guess - but has never been published or owned by Sun Media.
In some ways the relationship is strange because Sun newspapers compete against Post newspapers in some cities even though they're under common ownership once one gets high enough. Examples:
Calgary Sun (Sun Media) vs Calgary Herald (Post Media)
Edmonton Sun (Sun Media) vs Edmonton Journal (Post Media)
Ottawa Sun (Sun Media) vs Ottawa Citizen (Post Media)
and - more confusing because of the names of the papers -
The Province of Vancouver (Sun Media) vs Vancouver Sun (Post Media)
By and large, I'd say that even though they're under the same ownership, Post Media newspapers are generally looked on as more respectable than Sun newspapers, and they appeal to a different readership.
How that mixed up ownership situation impacts the slant of the Vancouver Sun and Douglas Todd in his interpretation of the survey is for readers to decide.
