With Transport Canada we had communication immediately following the accident. Then we were in regular communication throughout the 24th, 25th, 26th and 27th, until such time as the tracks were reopened for traffic.
I couldn't tell you specifically the exact frequency, but I can tell you that every single time we had a meaningful enough development we would contact the minister's office and they contacted us as well on their own just to make sure they stayed informed about the situation and the upcoming developments.
