Canadian National North of Prince George B.C.

Before Canadian National bought out B.C. Rail, they used to use run frieghts 6 times a week between Prince George and Fort St. John. Then 3 times a week between Chetwynd and Dawson Creek and 3 time a week between Fort St. John and Fort Nelson. Has this changed at all or are things different? Thanks. Inquiring minds and a former resident of that are wants to know.
