The ice strengthened bow is also good for ramming....
On a historical note, was Canadian expertise and experience used for route planning for the Arctic Convoys during WW2? I cannot imagine that anyone else (apart from free Norwegians or Danes) would had experience of routinely operating in waters that far North and that cold.
The Canadian contribution to winning the war at sea was massive and should never be forgotten. It was covered in the suitably named Canadian film Lifeline To Victory.
Sorry for the ever so slight tangent.
Here's a map of maximum ice extent in 2021. Notice how the area north of Norway and well east of Murmansk are ice free. This is the effect of the Gulf Stream. Now look at Canada and how far south the ice comes, and how the Arctic area is completely ice covered. The sea north of Norway may be "Arctic" in terms of latitude, but the operating conditions there are far less severe.
I don't know if Canadian seafarers were involved in advising the British admiralty in WWII. Given how tightly knit the Empire was in those days that may in fact not be an easy question to answer as such concepts as a separate Canadian citizenship didn't even exist in those days.
However have a look at this map again and keep it in mind when you are posting about a ship having "operated in the Arctic" when all it did was sail about north of Norway. Get into the "true" Arctic and the situation there is very different.
