Madam Chair, I'll give a general comment, if I may. I would suggest that different types of operating companies or various types of organizations have different challenges. A very large organization may be large, complex, and difficult to necessarily move quickly, and smaller operations have their own complexities, it's true. Some of them certainly have financial challenges, but of course, that applies to larger corporations in some cases as well.
In terms of the letter of safety advisory that was written by the Transportation Safety Board in regard to training of short-line railways, I'll ask Madam Brigitte Diogo to respond.
