the advice to "have an armed polar bear guard" contains the half truths of most gov't utterances.
as a working Canadian Citizen you are precluded from having a firearm inside of the park. BUT as a sainted native of the north, you can carry one right on in. we are not capping on the first nation here, it is just that they retain rights that fairly should be avail to all peoples. obvious, pure, raw discrimination is what it is.
thusly to be correctly prepared for the multiple polar bear encounters that you will have in that area (it is currently infested with them) you would need to hire a native guide. if you are on a snow machine or hunting or such, then you can probably find one. if you are traveling on foot, as was the sierra club group .... good luck. carrying a pack ? this is not something northern natives are going to do. they are simply not set up for it. it does not really pertain to the way the live every normal day up there.
going by leaky boat ? across open water laden with slabs of ice ? with a motor that sputters and low on fuel ?? native is the way to go. not a problem.
need to get somewhere by snow machine because the weather is too hideous for the helicopter ? sledding across half snow, half rocks, crossing creeks during runoff as full throttle, and can not see 40 feet in front of you ? that is sop on the way to school for an inuit child.
but carrying a pack ??? are you Out of your White Honky Mind. and leave us be, go Away, you are an idiot from the south.
and That is how they came to not have an armed guard.
now the fine minds in Ottawa have said, "they may need to look at the policy". ohh , that's nice. how reactive. they guy's already well chewed upon. it's not as if they were not well informed about this some years ago.
stereotypical bureaucratical incompetence getting people killed. but that is nothing new. is it ?
if you deployed a normal electrified fence, and the terrain was insufficiently conductive (as much of the arctic is...) it would not have had any effect. nor will an "electric fence" issue any kind of warning that your perimeter has been breached.
to have an workable shock fence, one needs multiple conductors strung a various heights. which it's a big mess to erect every afternoon.
rf field motion detectors are not effective in the wind. ir detectors fail to reliably pick up the very weak thermal signature of white bears. if interested, look around a bit, and if you are wanting any sort of warning, you'll find it takes a perimeter alarm to do the trick.
