On December 15, 2008, the Fifth Protocol to the tax treaty between Canada and the United States entered into force.

The Protocol makes many important changes, including:

  • a phased-in exemption from withholding tax on related party interest
  • an exemption from withholding tax on guarantee fees
  • new rules extending treaty benefits to U.S. limited liability companies in certain cases
  • new "anti-hybrid" rules that deny treaty benefits to certain payments from hybrid entities
  • Canada's first comprehensive "limitation on benefits" rules
  • a binding arbitration procedure for competent authority cases, and
  • a new "service permanent establishment" rule.

Details of these changes are discussed in previously issued Blakes Bulletins:
