The main CBC website has a running account of life aboard the Sir Wilfrid Laurier, a type 1100 medium duty icebreaker, currently on it's way to the annual Western Artic patrol. The Laurier is based out of Victoria, in British Columbia.
The Laurier is a bit dated but remains the workhorse of the fleet, and as JK mentioned below, has just been slated for electrical upgrades. The ship is twin fixed screw, diesel electric ship. Three Alco 251 V16 produce 6600kW of power.
Check out the progress at the CBC's website.
