Canadian with dual citizenship, Tax implications?

[Stevo Sun]

Hi everyone,

My wife is a dual citizen US/Canada. We live in Canada, and she does not hold any investment property because we heard some horror stories about dealing with US taxation. I wondered if there were any tax implications if she started investing in rental properties in Canada. I know the TFSA doesn't work for her because it gets taxed on the stateside. Are there any other tax implications we need to watch out for?
