Opinions vary, and it seems that there's no rhyme or reason to what works for what product.
Try a few listings on .ca and see if they do better, that's all I can suggest.
If you use the US turbolister, you can import the US listing, with the auctiva templates, edit the information and change the selling site to .ca and then re-list on .ca.
