The firm is recognized as one of Canada’s leading law firms in transfer pricing, both at the advisory and dispute resolution level. We assist clients in managing transfer pricing risks associated with ongoing operations, business restructurings and special transactions. We defend positions at any level from audit, through the administrative appeals level, to competent authority proceedings and, as needed and as a last resort, before the courts.

We also represent taxpayers seeking to apply for MAP, APA and other competent authority procedures.  Our lawyers work collaboratively with client teams in finance, tax and legal as well as their external advisors to provide effective solutions to their transfer pricing challenges and protect privileged exchanges.

Transfer pricing: audits and objections, federal and provincial court appeals and judicial review applications, MAPs, APAs, ACAPs.

Dispute resolution and tax controversy: complex audit defence in all corporate tax matters including scientific research and experimental development claims, as well as administrative objections, federal and provincial court appeals and judicial review applications.
