To strengthen your Canada visitor visa, your invitation letter must have your host’s personal details-full name, citizenship, address, and occupation; contact information phone, email, and address; and, of course, proof of their immigration status, namely, their citizenship or permanent residency. It should also explain very clearly your relationship with the host, supported with relevant documents such as photos or letters, outline financial support they will provide for your stay during the visit-period covering expenses such as travel, accommodation, and food, plus your proposed activities and destinations in Canada. These details make your application look authentic and well-prepared.
