I just found that my vinyl copy of French Record gives a partial translation:

Me, I walk under St Catherine
I take advantage if the subway's warmth
I don't have to see myself in shop windows
When it's thirty degrees below zero

Don't think that I'm an idiot
Because I don't drive a convertible
Glory is fairly useless
At the price if gas it's opressive

It's a long time that we've been politicos
Twenty years of war against mosquitoes

The sleeve also notes it was the first song co-written with Philippe Tatartcheff, a close friend since the sixties, a native of Timmins, a mining town in northern Ontario, formerly a student of French literature at La Sorbonne, now (in 1975?) a farmer and poet near Dunham Quebec.

I'd still like to know what 'been politicos' refers to. The 'events' in Paris in '68 perhaps. And north Ontario might explain the mosquitos - ISTR a song about those.

The French wiki piece notes 'there are no mosquitoes (under the street) even in summer'. So she's getting away from both cold and mosquitoes down there.
