How do I changed the language used by the Gnome spell checker?

I'm a Canadian, but often get American spelling suggestions from the spell checker in Ubuntu. How do I switch to a Canadian dictionary?

From ubuntu Mark B

• The spell checker is based on your Locale - if you switch it to en_CA (or en_GB if en_CA is not available) you should be more Canadian like spellings.

  Get a list of installed languages with the following:

  locale -a

  You can view your current selected locale with:

  locale

  Once you've selected the one which best suites you - you can update it here:

  sudoedit /etc/default/locale

  Be aware if an entry from locale -a ends with .utf8 it needs to be entered as .UTF-8 in the default locale.

  After you make those changes you'll need to reboot for them to apply.

• Marco Ceppi is right about this being based on the locale, but the easiest way to change this is through System -> Administration -> Language Support in the graphical user-interface (it will also make sure all the right packages are installed, etc.).
