I am a Canadian citizen but non tax-resident of Canada. I am currently working in China and paying my taxes there. I previously had an investment account with BMO Investor Line in Canada but they do not want to let me buy stocks anymore since I am not a tax resident of Canada anymore.
I am looking for other countries where I could open an investment account to buy stocks. However, I found it difficult to open a stock market account in other countries. In mainland China, I cannot open the stock market account. In Hong Kong, I cannot open the stock market account as they do not allow Canadians to have a stock market account there due to tax regulations.
In which countries would a non-tax resident Canadian could open an investment account, and where it would be advantageous?
Ideally, I would prefer to not pay tax in Canada (to avoid filling an income tax report) but in China or in another country.
Singapore? Other countries?
