Layton has proposed a February election. The motion will likely be tabled on November 24th.
An important point was made in the Canada.com article.
But it's unclear if the motion would be considered a traditional confidence matter, which could topple the government immediately. It's also unclear if the Liberals would be bound by anything but a true confidence motion.
I take it no one remembers what happened in May? The Liberals ignored the motion that was tabled then. There is no reason to assume this one would be any different.
