I am a 60 year old canadian resident with 250 000$ in an IRA. What are the tax implications of a 100% withdrawl vs a gradual withdrawl over 10 years.

The simple answer is that spreading it out over time will most likely reduce your tax liability vs. a lump-sum distribution. Would need to know more about your specific tax/income situation to get you specific numbers.
