Canuck CP uses Google Fonts and internet fonts. You can use a different font for Headers, Body text and Page Titles.
At the moment there are 33 fonts to choose from. I have done it this way because I feel that these fonts should be good for most users, and sticking in a list of all the Google Fonts is certainly overwhelming. Now if you find that the font you want is to use is not listed, I can set it up in the next update. The only requirement is that it be in the Google font library.
Please feel free to contact me with the font you would like to use, and I will try and get it in the next update.
