I think so.
In any event, "Law & Legislation" are among the keywords listed for an article entitled "The First External Auditors of the Hudson's Bay Company, 1866" by Gary F. Spraakman of York University, the notice for which flitted across my screen a couple of days ago. It appeared in the Accounting Historians' Journal last spring. In my
Admittedly I don't know a lot about the subject, but I am advised by those who do that accounting practices are not highlighted often enough in business history. When they are they can be quite key. I recall, for example, many years ago Michael Bliss attributing some of Joseph Flavelle's rise to prominence to the latter's innovation in accounting practice in the pork packing industry (note: not a snarky reference to war profiteering.)
Accounting history is certainly something Canadian legal historians would be well to consider, especially when studying issues of corporate law and governance. I haven't yet looked at any of the issues of the AHJ, but the abstract of Spraakman's article sounds as though it is something that would be very relevant to historians interested in the HBC, of whom there are now quite a number. Spraakman has also written on internal audit at the UBC.
