J immy Peter Einish was in a police cell more than 300 miles from home when he realised he needed to take control of his life. Trapped in a dark spiral of drinking and violence, he was locked up in Sept-Îles, a port on the north shore of the mighty St Lawrence River in the Canadian province of Quebec, for getting involved in a fight. “Something just clicked inside of me,” he remembers. “I just said ‘What am I doing to myself?’”

That was in the late 1980s. But it wasn’t until 1998 that Mr Einish finally overcame his addiction to alcohol. Since then, he has counselled dozens of others on the often long road to sobriety in Kawawachikamach, an indigenous community in northern Quebec only accessible by all-day train or a return flight costing C$1300 (£760).
