@noodle As I said above, I have forwarded a request to add extra lines to the T1135 form to our development team. However, a request like this, if it is acted upon, likely will not be completed this tax season.
In the meantime, you can try combining items if possible. Or you can NETFILE your T1 return and then print and mail your T1135 using the forms on the CRA website, and attach any extra forms that you need (the CRA form also only has limited lines).
