Unfortunately, it seems that GIMP does something to negate this capability. Interestingly GIMP does provide a "Page Setup" dialogue which is used to specify both paper and border size separately from the Canon driver. When using the "Page Setup" dialogue it appears as though GIMP does NOT allow the border values to be set to zero.
Did you tried to access what you cannot (because you don't see it) with the Tab key of your keyboard, you can switch/navigate between options with the tab key, then to tick an option use the space bar, use the space bar again and it will un-tick
When on a drop down option (like inch), use the arrow key up and/or down to see/use the next option (like mm etc...)
