CanadaTories got something like 55% of Protestants in 2011, so I would guess that even the United Church has a bit of a Tory lean and that Evangelicals vote something like 75-80% Tory. Some possible exceptions would be the Salvation Army (mostly in Newfoundland), and maybe Pentecostals.
Yeah, although the United Church has an "ultra-liberal" image I don't think its membership - which seems to be made up of largely small-town WASPs - is that left-wing really. Although there's a visible, urban, educated "Social Gospel" wing.
Anglicans I would guess are pretty similar, even though they're a bit more conservative than UCC. But I think they're a bit more overrepresented - or at least were - among the old WASP elite and a little less Social Gospel-y.
In Canada, Baptists are so well represeted in the Maritimes, I wonder if they lean Liberal or if they're still Conservative and their votes are just outweighed by everyone else.
As for the UK, there's a saying that the Labour Party was more influenced by Methodism than by Marx. Though wasn't Margaret Thatcher also a Methodist? Furthermore, I believe the Methodists in the UK are more socially conservative than the Church of England (unlike the situation in Canada with UCC/Anglicans) and their numbers have really really declined.
ETA: Back in the 19th and early 20th century, so-called Nonconformists supported the Liberals.
