There's a couple of us on here who know that country. I have property on the north end of the Dean Channel in British Columbia. It's some of the most beautiful scenery on the planet.

But in the 30+ years I've been flying that northwest corner of BC and into southeast Alaska, I still don't know where I'm gonna go when the engine quits. It's a vertical world. Straight up and down rock, and lots and lots of deep, cold water. Options are extremely limited.
Not to say don't fly it, in fact just the opposite. It's an awesome playground for GA, and everyone who loves flying backcountry should consider trips into that part of the world.
Just saying that when you do the WA to AK trip direct, even with long range fuel, you are cutting your options for Plan B down to a very bare IFR minimum. Especially in something slow and not de-iced like a C182. WX shuts down, you're forced to turn right and climb east into interior BC. And that's over big rock with low freezing levels, even in the summer. Engine quits and you're going swimming, unless the tides are out and you have a few hours of beach to use.
And, if something does go wrong, there you sit in Canada with your firearms, dealing with Customs with no preparation. Think it was four or five years ago a guy in a Comanche 260 lost an engine by Nanaimo, and stuffed it into a logging strip while flying non-stop from PAKT to KBLI. He had rifles and pistols with him, and Canada made him out to be an international terrorist with nukes, all because he didn't have the right paperwork (and $$$$ fees paid). It was ugly.
I'm not usually a Negative Nancy for flying, but that route single-engine is one I tell all but the most experienced not to do. Besides, the interior routes are too much fun to miss.
