Just to clarify, Madam Bateman, because you've raised this a number of times before, witnesses are not required to submit any written statements in advance of their testimony to committee. They're free to submit written statements if they so wish, but in some cases they don't, and we don't require them to.
The committee operates in both official languages and it does so orally. Translation is provided for members who wish to listen to the testimony or to the opening statement in either official language. No committee requires any witness to submit their opening statement or their testimony in writing.
