Hi,

Currently, Odoo does not offer an official payroll localization for Canada in either Version 18 or Version 19. The supported payroll localizations listed on Odoo’s documentation include countries like Belgium, India, and Indonesia, but Canada is not among them.

Community discussions and user confirmations also indicate that there is no built-in configuration for Canadian payroll features such as T4 forms or ROE reports. However, the Odoo Community Association (OCA) maintains a “payroll” repository on GitHub, which includes general payroll-related modules. These may serve as a foundation for customization, though they do not provide a complete Canadian payroll solution out of the box.

In summary, Canadian payroll must currently be implemented through third-party modules or custom development, as official support from Odoo is not yet available.

Hope it helps
