How to open a joint bank account in Canada, or add someone to yours
Quick summary
A joint account is a regular account that two or more people share. Everyone on it can usually deposit, withdraw and pay from it, and everyone shares the risk. To open one, both people agree and apply together. CIBC says its joint accounts are opened at a banking centre or by phone, not online. Next step: read what a joint account is and its risks.

How to open one, step by step
The FCAC says to talk with the other person first and agree how you will use the account, and to read the account agreement closely. It also says to ask a bank representative about the bank's joint account policies.
- Talk first. Agree who pays what, and what happens if you separate or one of you needs the money.
- Pick the account type and the bank. Ask about fees.
- Apply together. CIBC says you add your co-applicant on the application at a banking centre or by phone.
- Each person brings ID. CIBC lists up to two pieces of valid, original ID for a personal account application.
- Read the agreement and ask who can do what. Keep a copy.

How to add someone to an account you already have
The FCAC page does not explain how to add someone. CIBC does: visit a banking centre. All joint holders should agree to add another holder, and the person being added must agree too. CIBC says the person being added must be present and bring 1 piece of acceptable ID.
TD's page did not say how to open a joint or single account, who must be there or what ID is needed. It points you to a branch, an appointment or a call. Ask your own bank, because the steps differ.

If one holder dies
The FCAC says to ask what happens to the account if one holder dies. In some provinces and territories, banks may restrict access to some or all of the funds for a time, so a surviving holder may not be able to use the money right away. TD says the outcome depends on the account terms and what the holders chose when they opened it, and that some joint accounts have a right of survivorship.

Keep it safe
- Use your own login. The FCAC says sharing online banking passwords, even with family, may cost you protection against unauthorized transactions.
- Check the account often for payments you do not recognize.
- Be careful with e-Transfers. A sent e-Transfer cannot be reversed once the other person deposits it.
