How do taxes work when selling inherited stock?

You are only taxed on the capital gains the investments have earned since the original owner's date of death, not the total amount you cash out. However, finding the adjusted cost base for decades-old investments spread across multiple banks is incredibly difficult. This leaves executors guessing about how badly the estate will be taxed when they try to sell a portion of the shares.

“My mother died 3 weeks ago and i'm the executor. We are in canada. She had roughly $650,000 in non registered investments, $99000 in a RRIF and $250 in a TFSA. How badly will the estate be taxed? how do you figure out the ACB of investments that are about 60 years old and span 3 different banks?”source ↗

“Just want to make sure I have this right regarding selling inherited stock. Is this how it works?”source ↗

“Do I just check the stock price for that day and only take out 250,000 worth and then I won't be taxed. I'd only be taxed on capital gains of the 100,000 that it increased since date of death.”source ↗
