去年短登多伦多，听朋友说起报税的事，其中有一事不明，特此请较各位移友：我回国后参加了几个外商投资的大工程。工资不低同时交了不少税。我想，有没有必要等我再次登陆加拿大时申报海外收入，这样做会不会重复上税，对我是好处多还是坏处多？

小弟拜求指点！

you are supposed to file 2004 overseas income to Canada Revenue Agency www.ccra.ca before April 30, 2005, and depends on how much you earned and tax paid in China already, the worst case for you is pay the different to CCRA.
