Impressive voter turnout in Denmark (shame about the result)

I couldn't help but be impressed with the voter turnout in the recent Danish general election. 85.8%!
And here we are in Canada with a turnout hovering either side of 60% in recent federal elections, and closer to 50% in Ontario provincial elections (although Alberta managed to hit a low of 40% in their 2008 vote).
Whether or not you agree with the result of the vote (a centre-right coalition group, with the strongly right-wing, anti-immigration Danish People's Party as the second-largest single party in parliament), that is still undeniably impressive. So, what do we have to do to achieve that?
