Thanks for your comment! I will modify the text to reflect that! In Canada, all our packaging uses a capital L for litres and mL for millilitres. From a science perspective, the international conventions for litre is the capital L and also l. Most scientists adopted the capital L to avoid any confusion between l and 1. It used to be that millilitres were abbreviated with a little m and a little l but the l was cursive font to avoid any confusion with the number 1. All that to say that the little l is still widely used, even though the scientific community made a push for the capital L.
