Ottawa marked the 10th anniversary of the terrorist attack on Parliament Hill Tuesday — but for the family of the reservist who was killed that day, the memory is still raw.

Memorials and tributes are taking place across Ottawa on Tuesday to remember Cpl. Nathan Cirillo, an honour guard stationed at the National War Memorial, killed 10 years ago today.

The gunman then made his way down the street to Parliament Hill and entered Centre Block, where he fired multiple shots before he was killed. The attacks drew attention to security lapses on and around Parliament Hill.

Speaking of special teams, the Senators' power play has been nothing short of electric. With eight goals in their first five games, they are tied for the second-best power play in the NHL, only behind the undefeated Winnipeg Jets.
