Looks like the North American Tour for Three Days Grace just got a little more interesting.  Looks like former lead singer of 3DG, Adam Gontier, has left the group because of recent health issues.  Three Days Grace bass player, Brad Walst, will be joined on stage by his brother Matt on February 1st to kick off the tour.

According to the Three Days Grace website...

In response, Brad Walst stated: "We were surprised and distressed by Adam's sudden departure.  We are however very excited for this upcoming tour, and to have my brother Matt stepping in as lead singer."
