It's not up to me to comment on policies set by the government, but I can make recommendations on their implementation by the departments.
I could, therefore, communicate with the people at Statistics Canada, who are experts on statistics. However, if the agency isn't the focus of the audit I'm conducting, I won't make recommendations for the agency. That doesn't mean that I won't communicate with the deputy minister to share what we've observed and found in order to improve the performance of that government service.
