Russia to rule the Arctic?

Judging from this infographic at least. Note the number of icebreakers. 

Naval Power

I bring this up because Diane Francis was making the rounds flogging her new book, Merger of the Century, exhorting Canada to merge with the United States in order to protect its economic interests. I have not read the book so will not comment on its contents but if Russia wanted to make inroads in the Arctic today, it would have a naval advantage given the number of icebreakers.
