Which Canadian province is most socially conservative?

[King of Kensington]

I think it's New Brunswick or PEI.  I decided to cast a vote for NB.

Between the Prairie provinces, they're all pretty close I'd think.  Saskatchewan is a little more rural.  On the other hand, it's less Mennonite than Manitoba and doesn't have a Mormon presence like Alberta, though rural and small-town German Catholics and Ukrainian Catholics - large groups in rural Saskatchewan - can be quite socially conservative as well.

So what makes Saskatchewan in particular so socially conservative?

Evangelical population by province, 2011 NHS:

Newfoundland and Labrador  81,315  16%
Prince Edward Island  19,590  14.3%
Nova Scotia  140,585  15.5%
New Brunswick  131,655  17.9%
Quebec  294,090  3.8%
Ontario  1,605,965  12.7%
Manitoba  225,735  19.2%
Saskatchewan  147,840  14.7%
Alberta  596,020  16.7%
British Columbia  641,005  14.8%

(I followed the definition here: http://files.efc-canada.net/min/rc/cft/V01I02/Evangelicals_Canadian_Census.pdf)

In Newfoundland, it's dominated by Salvation Army and Pentecostals, Baptists dominate the Maritimes evangelical population, Ontario is pretty mixed and includes a lot of Black churches, Manitoba gets a boost from the Mennonites, the rest of the West is very mixed. 

Comparing the 3 Prairie provinces:

Manitoba is 19% evangelical, 21% mainline Protestant, 26% Catholic, and 26% no religion.

Saskatchewan is 15% evangelical, 26% mainline, 30% Catholic and 24% no religion.

Alberta is 17% evangelical, 16% mainline, 24% Catholic, and 30% no religion.

Membership in the Evangelical Fellowship of Canada

And Winnipeg makes up close to 60% of Manitoba's population.

Mormons make up 2% of Alberta's population which, although not evangelical, can be added to the social conservative constituency.  There are very few in other provinces.

Attendance at religious services by province and regional pockets, albeit from 2003:

BC and Quebec are the lowest; PEI, New Brunswick and Newfoundland are the highest.

"Bible belts" are evident in Atlantic Canada and the rural southern prairies in particular.

Very true.  The Maritimes have strong historic links to New England.  At the time of Confederation they were certainly stronger than they were to central Canada (and even today, many Maritimers see Boston as the "big city"). 

The Maritimes is part of country's poorest region (along with Newfoundland) and in some ways it's a bit New England meets the South (lots of Baptists, rural Black communities in Nova Scotia, etc.)

Northern Maine does resemble New Brunswick in a lot of ways, though most of Maine's population is in the southern part of the state that is more oriented towards Boston.

(I know Maritimes doesn't include Newfoundland, which is also poor and more religious, though it's less linked to New England.)

I posted all census agglomerations that are at least 20% evangelical in another thread.  I had forgotten to include Newfoundland and list again:

Steinbach MB  63.5% (Provencher)
Leamington ON  31.7% (Chatham-Kent-Essex)
Lacombe AB  31.7% (Wetaskiwin)
Kentville NS  31.3% (Kings-Hants)
Grand Falls-Windsor NF 31% (Bonavista-Gander-Grand Falls-Windsor)
Abbotsford BC  28.3% (Abbotsford)
Chilliwack BC  28.3% (Chilliwack-Fraser Canyon)
Swift Current SK  26.3% (Cypress Hill-Grasslands)
Fredericton NB 24.4% (Fredericton)
Norfolk ON  21.6% (Haldimand-Norfolk)
High River AB  21.6% (Macleod)
Sylvan Lake AB  20.9% (Red Deer)
Brooks AB  20.8% (Medicine Hat)
Lethbridge AB  20.8% (Lethbridge)
Truro NS  20.6% (Cumberland-Colchester-Musqudoboit Valley)
Chatham-Kent ON  20.2% (Chatham-Kent-Essex)
Wetaskiwin AB  20.2% (Wetaskiwin)
Red Deer AB  20.1% (Red Deer)
Salmon Arm BC  20.0% (Okanagan-Shuswap)

The evangelical Protestant population in Newfoundland is mostly Salvation Army and Pentecostal, and it's heavily concentrated around Grand Falls-Windsor.
