Giving money now can change what you have to live on later.
Start with the purpose
A home deposit, a one-time expense and ongoing support place different demands on your savings. Clarify the help you want to offer and when it would make the most difference.
Check what it costs to give
You may need to take out more than you plan to give. Selling investments or taking money from an RRSP can trigger tax. Work out what would leave your accounts and what your child would receive.
Protect your own choices
Allow for your retirement, care costs and other family needs. Keep some money for surprises. Check that helping today still leaves enough for your life later.
This situation does not set an affordable gift amount or recommend a legal arrangement. Your own needs and the source of the funds need a separate review.
