I splurged on a 1-year membership to Projection Lab.
I was happy to support the creator of it, it's a beautiful tool that's both intuitive, simple AND extremely customizable. (very rare to balance both)
It's an american program, but you can load in all the canadian accounts and tax brackets.
I'm happy with it however I will not be renewing after my 1-year membership because the program doesn't do everything I want (what is discussed above), optimize tax planning, avoid clawback, etc.
You can plan all kinds of draw down scenarios, but the program falls short of running through all the permutations for you and telling the user the most optimal way.
It's a power tool for visualizing accumulation, and cashflow, and scenario planning, if that's all you're looking for.
hoping Optimal continues to improve, might consider it in the future.
