According to Statscan, a majority of Chinese Canadians are of no religion. But there's a sizeable evangelical element that is seemingly growing.
Thing is, outside of a few rural pockets, evangelicalism in Canada is largely an immigrant phenomenon.
It might be different in say, the suburban counties in California with large Asian populations. Does integration into "blue state liberalism" inhibit the influence of evangelical churches among Chinese Americans?
Nonwhite evangelicals are consistently more left wing than white evangelicals in the US. With Asian Americans this is actually true for all subgroups of Christianity. Can’t find the supporting Pew Research article at the moment. http://www.pewsocialtrends.org/2012/06/19/chapter-7-religious-affiliation-beliefs-and-practices/
Among my RL social network, there is a politically outspoken subgroup of US-born Asian-American “evangelical Protestant” Christians who are highly social justice oriented and largely align with the Religious Left. This group is relatively young and is mostly comprised of college students and recent college grads. The majority seems fairly apolitical, but not in a way that would make them susceptible to supporting the current GOP.
To add to this, I would say there is a generational divide among Asian-American evangelicals with first generation immigrants being more politically split (though many are still Democratic due to economics and immigration as well as participation in pro-democracy movements in countries such as South Korea) while second generation individuals are more distinctly left leaning due to heavy concentration in blue states and areas combined with high rates of post-secondary education.
