I was just looking up lightkeeper positions in my province. Unfortunately no openings right now. But it would be an interesting job for an introvert like myself.
Not to imply real knowledge of lightkeeping - but that sounds far less precarious, dispossessing, onerous, and dangerous than being one of the Puesteros.
In the US, IIRC, you had to be a member of the Coast Guard. Isn't it the same in Canada?
AFAIK no - you need basic first aid, a radio operator license, and other things like that. But I actually haven't looked at it that seriously since there aren't any openings right now.
