I've done good at namedrive for my .ca and recently tried parked for them but so far the returns have been minimal. I should mention that my .com's at parked have returned about 5-7 times daily rev. one in particular (a dot com) was making 50 cents to 3$ a day is now hitting 10-22$ p/day consistently.
I've rarely moved my .ca around, but might just try fab and may report back with my results.
I've also used Sedo and been happy with them - but they can't do .ca's with provincial extensions (ie. xyz.bc.ca .... I park those at namedrive)
I also like the fact sedo has a link to sell the domain as well. You have to special request that at namedrive. Do fab and parked have easy "buy this domain" links?
parked has the option i believe. plus you can add content to the page (text) I've had parked a long time but only now am exploring the options so someone else can elaborate for me.
You can also upload your own image for the parked page template.
I've had the best results for .ca with namedrive. Tried parked and sedo without success. When I have some time I'll try and toss up some ppc templates with either google or ypn.
