SIR/E-Discovery

A supplementary information request (SIR) is a detailed information request issued by the Competition Bureau as part of a merger review. Responding to an SIR is a critical part of gaining clearance for a complex merger and requires a team of specialized and experienced counsel.

The Blakes Competition, Antitrust & Foreign Investment group, repeatedly acknowledged as a leading competition practice in Canada, has successfully guided its clients through SIR processes for many of the most high-profile and complex transactions in Canadian history (beginning in 2009 with the first SIR to have been issued by the Bureau).
