A blog post from LAC announces transcription of some paper-based finding aids that were previously available only in the Reference Room at 395 Wellington Street. Chances are they won't be of interest unless your ancestor was somehow involved with the organisation, but just in case they are:
- Royal Canadian Mounted Police (RCMP) Administrative Records
- Supreme Court Case Files
- Canadian Hydrographic Service
