Maybe 2007 when production of the GTO will come to North America. The Aussie's have a maximum production of 18,000 per year. In 2005 Holden will only produce 12,000 GTO's ending in May to start the 2006 model year.
The current platform does not conform to Canadian specs. The gas tank location especially and crash test. They need to put more pressure on GMH to build it to their specs before they can be imported to Canada.
