You can display the website for the Defi in either English or French.
Typically, for rallies in Quebec, the information is posted in French first and, after translation, posted in English, a week or so later.
The Supp. Regs. for this year's rally are now posted in French. Try reading the regs in French. The general information for every rally is about the same, so you should be able to get the gist of what they say. Or, run them through a French/English translation tool.
The rally starts Friday, September 10, in Ste-Agathe, Quebec which is about an hour north of Montreal. There is a full recce before the rally.
If you check back into the website, over the next while, you will soon find more information in English.
I highly recommend this event. Great roads, spectators and rally atmospshere.
