What's the meaning of your processed passport has been dispatched?
This statement means that Canada Visa Office has completed the verification process of your passport. Once the process is completed, your passport is sent back to VFS centre from the Canadian Embassy. In case you have opted and paid for courier service, your passport will be dispatched to your address. Otherwise, you will personally have to go to VFS centre to collect your passport. This message does not indicate whether your visa application is selected or rejected. In that case, you will get a personal notification via mail from Canada Immigration Office notifying you of the status of your visa application. The message has no inclination of approval or refusal of your visa application. So you can stop worrying about it.
