Adding someone to a bank account in Canada usually means either opening a joint account or designating an authorized user, depending on your bank and your relationship with the person. The exact steps vary by institution, but the overall process is similar across major Canadian banks such as RBC, TD, Scotiabank, BMO, and CIBC, as well as online banks such as EQ Bank.
Decide whether you need a joint account or an authorized user
A joint bank account is legally shared, meaning both names appear on the account and both people have equal rights to deposit, withdraw, and manage the funds. This is commonly used by couples, family members, or business partners who share regular expenses.
An authorized user (sometimes called a secondary signer) has permission to perform transactions but is not a legal owner. Ownership stays with the primary account holder, which can be useful if you want to give a family member or caregiver limited access without changing legal liability.
Basic documents and requirements
To add someone, both you and the other person must normally provide standard identification and financial‑system information to the bank. Typical requirements include:
-
Government‑issued photo ID (for example, driver’s licence, passport, or provincial ID card).
-
Social Insurance Number (SIN) for each account holder or authorized user.
-
Proof of address, such as a utility bill or recent bank statement.
Some banks may also ask for a small initial deposit or proof of income, especially for joint chequing or savings accounts.
How to add someone at a Canadian bank
Most banks let you do this in‑person at a branch, by phone, or through online banking, though the exact options depend on the institution.
-
Contact your bank
-
Call customer service or visit your local branch to ask whether they allow adding a joint owner or authorized user to an existing account or if you must open a new joint account.
-
Ask about any fees, minimum deposit requirements, or tax implications (for example, joint accounts can affect estate planning and Canada Revenue Agency reporting).
-
-
Prepare documents and details
-
Gather both your own documents and the other person’s ID, SIN, and proof of address.
-
Decide how the account will be titled (e.g., “you and spouse” vs “you OR spouse”) as this affects who can sign and what happens if one owner dies.
-
-
Initiate the change
-
In‑person: Both parties usually attend a branch, sign signature cards and account‑opening forms, and review the terms of the joint account or authorized‑user agreement.
-
Online or mobile: Some banks allow you to open a joint account or invite another person through online banking or an app, then complete the verification steps together.
-
-
Review access and permissions
-
Confirm what the new holder can do: full withdrawals, bill payments, transfers, overdrafts, etc.
-
Some banks let you set spending limits or restrict certain features for authorized users.

Things to consider before adding someone
Because joint accounts legally bind both parties, it is important to understand the risks and responsibilities. Joint owners share equal liability for overdrafts, loans tied to the account, and potential tax or creditor issues. Misuse of the account—whether by you or the other person—can damage your credit or lead to disputes.
Before adding someone, discuss how the money will be used, who will manage it, and what happens if your relationship changes (for example, in a separation or death). If you are only giving someone temporary access, an authorized user may be safer than a full joint account.
If you are unsure which option fits your situation in Canada, it is wise to speak with a bank representative or a financial advisor to choose the structure that best protects your finances and goals.
