There are many reasons for these regional variances. Over the past two decades, British Columbia has positioned itself as closest to secularism than any other region of Canada. Fewer British Columbians describe themselves as having “a religion” every time the census rolls around. Still, the last municipal election saw candidates running for school board seats – and winning – after outlining creationist views. Quebec has always been a land of contrasts when it comes to religion. The presence of a crucifix inside the National Assembly is debated extensively in a province where fewer residents are attending church services than ever before.The odd thing here is that the writer of the piece has invoked a non-sequitur in the interpretation of the data, it seems. He remarks that 55% of residents of BC would "keep creationism out of schools," but that conclusion doesn't follow from any of the graphs presented. That is not the question asked. The questions being asked are whether or not humans evolved or were created within the last 10,000 years. While it is quite true that the two concepts are similar, one does not necessarily follow from the other.
Furthermore, it is not clear where he is getting his 55% number from, nor where he concludes that BC is leading the pack. Eyeballing the graphs seems to indicate that BC is behind Alberta and Quebec in their acceptance of human evolution.
I am not sure I would put a lot of faith in this.
