加拿大的法律我不知道，在美國轉trust不是tax event

Usually the lawyer establish a revocable trust, and trasnfer all asset into the trust.   A revocable trust means the owner retains full control of asset in the trust, there is no change of control therefore it is not a tax event in US. 

When the owner dies, the revocable trust becomes an irrevocable trust, that's a tax event because there is transfer of control. But in US all asset receives step-up basis so all the capital gain acquired before the death are wiped out.  So the asset at the time of death has no capital gain due to step-up basis.  The only tax due is estate tax (遺產稅），which is 0% for asset under 11 million per person.
