This form ships as a flat PDF with no interactive fields, so field-by-field online filling is not available. Open it in the editor to type onto the page, or download the official PDF. The Canada Revenue Agency also publishes a fillable version on its own site. That one is encrypted and built for Adobe Reader, so it will not fill here.
