Hey Sylvain,
You can download the CLUPA shapefile through Land Information Ontario. The shapefile can be imported into Google Earth (select "ESRI shape" as the format in the import dialogue).
https://www.javacoeapp.lrc.gov.on.ca/ge ... /main.homeIn the "What?" search bar, enter "CLUPA" and the file you'll want is "CLUPA Provincial."
Click Download, then enter your name, organization (anything), and email, and you'll be sent a download link not too long afterward.
If you need any help, just reply here (so others can see) and I'll get back to you.
Jon
