I was wondering how many border crossings there are between Canada and the United States. Altogether there are 109 crossing areas. My question is, since Canada is so large of a country and the border crossings are located along the Canada-U.S. area, then how is the northern area of Canada being kept secure?

Canada's Answer to Security in Northern Canada:

• Alert, Nunavut is the most Northern part of Canada. "It also has many temporary inhabitants as it hosts a military signals intelligence radio receiving facility at Canadian Forces Station Alert (CFS Alert)(Wikipedia)."

• Canada says will defend its Arctic

(AFP) — The Canadian government on Friday reaffirmed its Arctic claims, saying it will defend its northern territories and waters after Russia earlier announced plans to militarize the North.
"Canada is an Arctic power," Catherine Loubier, a spokeswoman for Foreign Affairs Minister Lawrence Cannon, said in an email to AFP.
"The government is engaged in protecting the security of Canada and in exercising its sovereignty in the North, including Canadian waters," she said.

Loubier pointed to the planned acquisition of Arctic patrol vessels, construction of a deep water port and eavesdropping network in the region, annual military exercises and boosting the number Inuit Arctic rangers keeping on eye on goings-on along its northern frontier.
Earlier, Russia announced plans to turn the Arctic into its "leading strategic resource base" by 2020 and station troops there, documents showed, as nations race to stake a claim to the oil-rich region.

The country's strategy for the Arctic through 2020 -- adopted last year and now published on the national security council website -- says one of Russia's main goals for the region is to put troops in its Arctic zone "capable of ensuring military security."

Do you think Canada's Arctic is secure enough against other countries?
