The April-May cover story of Canada's History is Titanic: 100 Years After — Canada's Role Remembered. It's not the first time the magazine has looked at this tragic event, but a centenary is a timely opportunity to reflect again.

Many organizations have found ways to honour the passengers of Titanic, from museum exhibits to memorial cruises, train trips, books and movies. Canadian director James Cameron is re-releasing his 1997 blockbuster in a 3D version.

Julian Fellowes, creator of Downton Abbey, has written a re-telling of Titanic that is premiering in Canada as a four-part series (you can catch up on past episodes online). It's concluding episode will air on April 11th. Scroll down below and you can watch a trailer of the movie and view the photo gallery slideshow of scenes from the movie.

We've also included a National Geographic interview with Bob Ballard, the man credited with finding Titanic during a U.S. navy mission in 1985.

You can see Titanic in technicolour thanks to a young Toronto artist bringing the Titanic disaster back to life via a series of paintings he has created to commemorate the centennial of the ship's sinking. Matthew Chapman's solo show at the Toronto Arts & Letters Club will continue until April 28.
