As Martin mentioned earlier, signage would be in both official languages, so travellers would be able to understand what their rights and obligations are in both official languages.
That takes us back to one of those factors in terms of the unreasonable delay and the discussion around that. There are a number of factors taken into consideration in making sure that the traveller is not detained for an unreasonable length of time, and one of them would be language barriers. That would be something, again, that CBP would need to look at in the withdrawal context.
As Martin said, as they look at the officers they bring to Canada, they do look at language, so that's something they'll need to look at in terms of ensuring capacity.
