I’ve been working on a project where I wanted to map some data based on the Canadian province boundary. After some research I found the Boundary files from Statistics Canada that provide cartographic and digital maps in three formats:
- ArcInfo ® (.shp)
- Geography Markup Language (.gml)
- MapInfo ® (.tab)
and google refine does not support any of those format 
So I found and tested two file map converter exists:
- http://converter.mygeodata.eu to convert from .gml to .kml and then import to google fusion table the surface.kml file.
- http://www.shpescape.com to import .shp directly to fusion table.
Have fun!
