Thank you very much for the question, honourable member. It allows me to clarify that precisely.
In an effort to reduce costs for communication and to keep our team and our principals connected to Canada and each other during a visit, one of the tools we use is called mobile pucks. They are a mobile Wi-Fi or a Mi-Fi, which we have in the office of protocol. We can reuse them in every visit in the future, and they allow us to avoid roaming charges, which many of us have noted can be very high, particularly when travelling internationally. They also allow us to make bulk purchases of cheaper SIM cards, which are then added to these Mi-Fi pucks.
On a number of invoices, you'll see Wi-Fi or mobile charges. That's what that refers to.
With respect to the question of comparability to previous visits, I don't have the level of detail for previous visits before me. However, I can reassure the honourable member that we look at the situation in each country and the destination based on what the roaming charges would be versus the cost of using the pucks that we have and taking them with us from Canada. That's always part of our effort to keep those costs under control.
