Visitors from some countries may need a Letter of Invitation to be considered for a visitor’s visa. With the exception of the parent and grandparent super visa, issuing an invitation DOES NOT mean that you are legally or financially responsible for your visitor upon their arrival. However, you must intend to keep any promises of assistance you make in the letter. This letter is a lot more detailed than your standard invite to a backyard barbeque, but the basic principles are the same. It must include personal information about you and about the person you are inviting to Canada.
