Reno, I've used Elements years back now and do not recall ever using the Canvas Sizing in the version I had, but I found this on a web post that says that the feature was in Elements at least by 6.0 version;
In Photoshop Elements 6.0, the different options can be seen by opening a file to display an image and from the menu at the top, selecting ‘Image’ ‘Resize’.
* ‘Canvas Size’ will allow the dimensions of the drawing board to be changed
* ‘Image Size’ will allow the dimensions of both the image and canvas to be changed together – and for the resolution to be changed.
If there is a requirement to add a number of images to the canvas, or if the canvas needs to be made bigger, without changing the size of the image (for example, if a border is required around a photograph, then Canvas Size should be changed.)
The canvas size can be changed in many directions – extending to the right, to the left, up, down or proportionally all around the image. Once the canvas has been extended, the image will sit within the canvas with space around. If the canvas size is reduced, the image will be cropped to fit on the drawing board.
