mj, no need to use Google translate in this case.
The eBay Canada web site has identical help pages in English and French with the French Canada site having a prefix of cafr added in the web page URL.
Your link on English eBay.ca Canada
http://pages.ebay.ca/help/buy/bidding-overview.html#change
Same link on French eBay.ca Canada
http://pages.cafr.ebay.ca/help/buy/bidding-overview.html#change
You can get to the French version by two ways. The quick way is to go to the Canada site flag at the top of the help page, hover over it and a drop down list of French Canada site will appear and click on it. This will switch to the equivalent web page in French. The second way is to manually add the cafr in the browser URL address bar and press enter.
Works for almost every eBay Canada web page when I tried it over the years. Some exceptions of course like most of these English Canada community forum pages.
