I don't really specialy know for the rest of the world about the decrease of religion but the increase in science and technology. But Quebec got some event that lead to it.
This is probably the biggest contributing factor to religion dying out. In the old days, people were intrigued at how things worked. Since, they didn't have the technology and science as we do now, they weren't able to answer to questions with logic.
So they came up with a way to explain it. Create gods who created them. Without science to really prove the facts, it was easy to believe in gods which were the only explanation to phenomenons such as "Why does the sun set and rise?" which the Egyptians explained by saying it was dung beetles, the servants of Rah who rolled it across the sky (There are actually many other explanations in Egyptian mythology).
Now, we can prove that the Sun is a mass compilation of gas that burns and we are orbiting the Sun due to gravity, etc. through science. When we have our own way to prove things, god doesn't seem to be too big a deal anymore and seems less believable.
