Here are the means from a recent survey we did by region (respondents were asked to rank how liberal or conservative they were one a scale from 1 to 7)
BC: 3.57
AB: 4.41
SK: 4.28
MB: 3.82
ON: 3.55
QC: 3.52
Atl: 3.52
Now, this is really only a determiner of how conservative each province is. It's clear from the partisan means that Liberals were selecting lower numbers than New Democrats. If it were a survey where I wrote the questions, I would have used the term 'progressive' rather than liberal.
From the same survey, we did an openness index (my boss has a huge interest in this measurement), which basically measures authoritarian tendencies. The lower the number, the more authoritarian the respondent. Here are the provincial means:
BC 5.90
AB 5.39
SK 4.59
MB 5.26
ON 5.83
QC 5.63
Atl 6.09
Atlantic Canada lives up to its reputation as being a very friendly place. No surprise, Quebec doesn't fair well there.
