Hi, I noticed that when I run time machine and have myself dying at 90 but my wife living to 100, my account balances for my non-registered and registered accounts continue to accumulate rather than being transferred to my spouse. Is there any way to transfer the assets to my spouse on death?

What happens at your death is your accounts are inherited fully by your spouse, but we don’t transfer the investments to her accounts. They might be deemed disposed where appropriate (non-joint, non-registered investments) for your final tax/probate bill, and the tax basis of the investments is thus also inherited by the spouse.  The account ownership is changed from you (or Joint) to solely hers.  You don’t own it anymore, she does. She can use it as her own, and whatever taxes it attracts will also be solely hers. Make sense?
