I use the Garmin InReach Mini.  It is small, it pairs up with my cell phone, and it does the job I need it to do. It's reasonably priced and the annual fees aren't that bad, either. Primarily, I use it to send messages to home or to other paddlers I'm travelling with in the park. I have also found its weather forecasting to be far more reliable than the CBC reports I can get on the radio. As far as the GPS function itself, well, I guess I use Gaia as much or more than InReach mapping... and you don't even need a separate GPS device for it to work.  Gaia operates nicely on the GPS function built into most cell phones. In any case, for mapping, I prefer working off of a Fisher or McKenzie map.  I generally only refer to an electronic device when there is some doubt about my exact location.  Also, there is less "glare" on an actual map.  Morning sunshine can quickly obscure the face of your electronic device.  That doesn't happen with an actual map.

That's the short version re: how I handle it, anyhow.

P.S. If you're travelling on the north side of Quetico, there's at least a decent chance you might actually have cell service due to the recently erected tower near Nym Lake.  I spent 9 days on Batchewaung this past Spring and had cell service on most days.  I generally don't appreciate that sort of "progress" but it proved to be invaluable this year when we needed an airlift out due to injury.
