Safest way to handle this is contact IRCC and ask them. There are many ppl here who did it differently. But this shouldn't be issue anymore with Q11 like was back in October 2017
Hi Reddy, Open a new form and go to the page having Q11. and start typing the continuation part . Then print out that page and you can attach it with your existing forms and mark on top continuation. Also change the page numbers like put 5/7 and again 5/7 ( continuation)
