As a returning MP who has had four years of vacation, I am now remembering that there are resources for translation. If documents are provided ahead of time to the clerk, they will be prepared and ready for the meeting. If someone arrives with a document, it may take a couple of days to get it translated, so they may make their presentation orally and then the document will be entered into the committee's work once it's in translation.
On January 18th, 2016. See this statement in context.
