Being a deemed non-resident for canadian Tax purposes

I became a non-resident for tax purposes too.
I had the help from a lawyer and an accountant, which I highly recommend. They knew exactly what to do and the process was relatively straightforward.

I had my Canadian investments transferred to a trust in my mother's name.

There is no better way to handle your tax and business accounting than the NOBLE way.

In cross-border tax matters it is ALWAYS advisable to have the same person/firm prepare returns for BOTH jurisdictions. Since this firm's site admits only to preparing Cdn tax returns, it would not be the best choice for preparing and implementing an integrated cross-border tax/financial strategy.
Kinda like going to a tailor who only sells suit jackets, but can't do pants.

So, indeed, there are better ways.

But a valiant attempt at drumming up free business though. Kudos.
