The organizations want to find out whether Toronto Mayor Rob Ford has a connection to members of the "Dixie City Bloods" gang, the Canadian Broadcasting Corp. reported Tuesday.
"This is of great public interest as it may relate to allegations that the mayor of Toronto has been associated with members of a criminal organization," the court application said.
Police in Toronto and Windsor, Canada, arrested 43 people last month in an investigation dubbed "Project Traveller."
Two of the men arrested were pictured in a photograph with Ford.
The raids came weeks after reports emerged Ford was caught on video smoking a crack pipe. The mayor has denied the allegation and said such a video does not exist.
A U.S. website called Gawker raised $200,000 to purchase a copy of the video but was never able to secure one.
CBC said it has not seen the video and cannot verify if one even exists.
