Can I fly a glider in Europe on a Canadian Glider License?
In general, it is difficult to convert to EASA. You can find more information here however I suspect the easiest method will simply be for you to phone them up. 

I think the bureaucracy will probably be more hassle than it's worth. It's not like Transport Canada where you can just get a FLVC (Foreign Licence Validation Certificate) or whatever (that was a pleasent suprise after our CAA in the UK!).
