I am a US investment advisor with a client who’s two sisters are Canadian citizens and reside in Canada. The two sisters would also like to utilize my investment services and invest in our stock, bonds, mutual funds, etc. portfolios. They asked me what the tax consequences might be. Is the answer similar to your explanation in your video about Canadians owning real estate in Florida? They simply will file a U.S tax return and then take a Foreign Tax Credit against their Canadian return for any U.S. taxes paid? Thanks for your help!
