In Canada, we don't worry about religion or private life of politicians (e.g., I don't know how many children our Prime Minister has). As long as his policies are OK, his religion is his affair. His policies on issues such as gay marriage, abortion, contraception, universal health care etc. are in line with those of most Canadians.
Since becoming the Prime Minister, he has not tried to ban gay marriage or restrict abortion in any manner. That is good enough for me.
