Albertans go to the polls today, and it's expected to be a battle between the Progressive Conservatives, and the province's new Wildrose party. Many are watching to see if Wildrose, led by Danielle Smith, can end the Tories' four-decade-long hold on power - or if PC leader Alison Redford can hold off a Wildrose surge by attracting supporters if the Liberals and the NDP. We'll have the latest on the race - and why the entire country should be paying attention to the results tonight. (CBC News Network will have live results as soon as the polls close - at 8 p.m. MT/10 p.m. ET.)

And there's another big story developing out of Alberta:   Travis Vader has been charged with two counts of first-degree murder in the deaths of Lyle and Marie McCann, an elderly couple from St. Albert, Alta., who disappeared while on a trip in 2010.  Their bodies have never been found. The RCMP believes the couple was killed the day they were seen filling up their motorhome before a trip to British Columbia. Tonight we'll have reaction from the couples son, Brett McCann.

In Quebec, the education minister is calling for a truce and a peaceful end to an 11-week-long strike by students. But it's not only the government who says it's had enough of the demonstrations. We'll talk to one Montreal student who argues its time to end the protests.

Plus, the search for the remains of a missing boy has come up empty - again. Six-year-old Etan Patz disappeared on his way to school 33 years ago - terrifying parents across the continent, and sparking a movement to help find missing kids. FBI and police in Manhattan were searching a basement for possible remains for days, but didn't find any significant clues. Tonight we'll look at how you keep hope alive, after decades of waiting.

Mark is on assignment this week. Rosemary Barton is hosting tonight. Tune in at 8 p.m. ET on CBC News Network.
