Hi there, I am a Hong Kong/Canadian Citizen. I can speak fluent Cantonese but my reading and writing is quite basic. Do you have any books and cds or work book that I can improve writing and reading?

I'd actually really like to know this, too.

I haven't seen any, but you may have luck asking on an Asian board; there may be software that is readily available in that part of the world, but isn't really marketed much in America/Canada.

Do you mean reading in Cantonese? Everyone in China uses the same writing system so you should be able to find it anywhere. Once you've grasped the relationship between Mandarin and Cantonese it should be no problem to alternate between the two.
