Unfortunately, Canadian laws allow us to issue these visas solely for the period during which the applicant's passport is valid. If it's only one year, the multiple-entry opportunity is applicable only for one year. However, it's applicable for three years if the applicant's passport is valid for three years.
We're going to use the example of Mexico to encourage our officers more. For us, the biggest problem is the cost difference between single and multiple entries. There's also work to be done with our applicants. A number of them don't want to request multiple-entry visas.
