Hey MarieAnne,
ok, so you got 5 different designs for your page and more domainnames that you want to point to one of your designs. This is perfectly ok, you should only watch a few things.
I made a quick check on canadafur.com. It does not redirect with a 301 statuscode, but with a 302 (temp redirect), you should change that to 301 here is more on statuscodes: http://www.seomoz.org/learn-seo/http-status-codes
I also noticed, that furcouncil.com does not have a rel canonical. This is optional, but in a scenario you are describing it realy gives you security not make a mistak. What you should do is: rel="canonical" href="http: yourdomainhere.tld/page" /> in the header of each of your pages. This will tell the searchengines that yourdomainhere.tld/page is the version you want to display and what they should index and rank.
Why to do this? If you screw up one of the redirects it could happen that the exactly same page is one time crawled and indexed on yourdomain and one time on anotherdomain, thus creating duplicate content.
