9. When, upon petition to that effect, it is shown to the Superior Court or to one of the judges thereof, charged with the administration of justice in the district, that a court of any other Province of Canada, or of any other British possession, or of a foreign country, before which any civil or commercial case is pending, desires to have the evidence of any party or witness in the district, such court or judge may order that such party or witness may be examined under oath, either by means of question in writing or otherwise, before any person mentioned in the said order, and may summon, by the same or by a subsequent order, such party or witness to appear for examination, and may order him to produce any writing or document mentioned in the order, or any other writing or document relating to the matter, and which may be in his possession.
The same rule applies, with the necessary modifications, when an inquiry commission instituted by the Governor General in Council or by the Lieutenant-Governor in Council of another province of Canada desires to have the evidence of a witness.
