namespro.ca is the registrar i sent my sister and brother to, and friends. Their prices are maybe 1$ more than the cheapest registrars in canada but their service is among the best. Viewing bulk domains is an easy process and security great. They have integrity as well. I also find dns settings arent placed in some drawer waiting to be submitted like some of the older registrars do.
My other favorite registrar is baremetal.com located out west. Integrity is tops, pricing is equal to namespro, security and support are top of the line.
For the cheapest price and security i use 10dollar. Possibly one of the few with bulk renewal and dns setting management. Although 10dollar's price is the lowest by about a dollar I only keep 1 or 2 hundred domains there. I have an equal amount at namespro and baremetal.
If I had to choose a registrar from these three above to place all my .ca domains, I would choose baremetal.com without hesitation.
I have domains with sibername and no-name registrars through pool but I'm always transferring them out. It seems I get penalized by sibername with tbr when I do move them out and have even gotten an email from the owner telling me that people with fewer domains in their account at sibername get second fiddle in tied bids on tbr day. As a result I have used them for tbr 1 time (last week) in the past year. My introduction to sibername was a double dip on my credit card for 200$, when i walked into their office it was a virtual post office on slater.
As for pool. I dont trust them and their shell companies (assorted registrars). I use them on occasion just to keep in the know. I won 4 domains with them the past year and each time the wait for dns settings and control is too long. while they earn revenue on parking with my domains i sit and wait. I phoned them this morning for a domain i won a month ago. its parked on some mass parksite with a direct link to another domain that happens to be very similar to the domain i won.
namespro.ca (A-plus)
baremetal.com (A-plus)
10dollar.ca (Adequate)
the pool.com family (avoid)
