Marie, a blog-reader from Gatineau, sent me a link to a fabulous resource for everyone in the region: an on-line directory of environmentally-friendly shops and services on the Quebec side of the river. The Green Directory (Le Bottin Vert) includes a guide to green living in Gatineau with lots of useful links, as well as a searchable directory of where to find green goods and services and where to bring used goods for re-use or recycling.
The Green Directory is a service provided by the City of Gatineau:
The Green Directory for the English version.
Le Bottin Vert for the French version.
Green Living Ottawa 
The link to the English site doesn’t connect. Here’s the correct link: http://www.gatineau.ca/etc/onlineservice.asp?t=The Green directory&u=/servicesenligne/bottin_vert/index.en.htm
