As I think Mr. Landry previously mentioned, one CN crew had a road accident in the snow conditions, and it was delayed in responding. Another crew did respond to the site via a vehicle referred to as a hi-rail, but at that time, due to the winds, they determined that they couldn't cut it at that time.
There was another tree down in front of train 69 at this point, so that crew relocated to move the tree they could to advance train 69. All of this is to say that CN was attempting to move the tree and did access the train on at least two occasions via hi-rail, but those emergency crews were performing activities to keep the network fluid, and that allowed our other trains to proceed.
