What exit taxes are you talking about? I’ve moved abroad twice, I don’t recall paying an exit tax. I did have to liquidate rrsp accounts which hurt, but there wasn’t really a loss as I didn’t pay tax on that money.
There is no exit tax.
There are two different ways to sever ties to Canada:
1. Renounce your residency
2. Renounce your citizenship
Both require you to liquidate or assess your Canadian assets at Fair Market Value and pay whatever capital gains taxes are owed to government. Also settle your income tax bill before you leave. Most people who do not have real estate investments or stocks, and have income tax deducted at source by their employer will probably not pay any taxes at all when they renounce residency/citizenship. Principal real estate cap gains exemption still holds.
