If you are using Canhost.ca's DNS servers
You can setup URL redirection under the "My DNS" section in your client area.
To do this please add a new record and set the type to URL, for the "Content" section you need to put in the full URL including http://
eg. host=redirect.domain.com type=URL content=http://www.domain.com/redirect.php
If you have any questions about URL redirection please open a support ticket through your Canhost.ca client area.
