No, we have not conducted the same degree of formal visa review that we have done in other circumstances. We have engaged in a number of technical trips to Mexico and, in combination with the Canada Border Services Agency and Global Affairs Canada, we are working with Mexican officials to identify elements we can undertake to reduce the risk of a visa lift and mitigate security and other concerns. A formal visa review, as it is normally done, has not yet been conducted.
