Versions of s. 491(1)

A court holding a formal investigation under this Part has the power of summoning before it any person and of requiring him to give evidence on oath, either orally or in writing, and to produce such documents and things as the court deems requisite to the full investigation of the matters into which it is appointed to examine, and it has the same power to enforce the attendance of witnesses and to compel them to give evidence as is vested in any court of justice in civil cases.
