The process of a TRP application depends on which country you belong to. Residents of some countries require an eTA (Electronic Travel Authorization), and some require a Visa to enter Canada.
Applying for a Visa requires the country
Applying from an eTA-required country
Applicants must apply for a visitor visa, including some supporting documents demonstrating why they’re admissible and why visiting Canada is justified for them.
IRCC might issue you a temporary resident permit if your eTA is refused, but its approval may depend on the nature of the application. Your own country’s visa office may have its application forms for applying for a TRP.
Length of a Temporary Resident Permit
There is no definite length of an issued Temporary Resident Permit, which usually lasts until your justified visit to Canada.
How much does a Temporary Resident Permit cost?
A temporary resident permit application has a processing fee of 200$. This fee is not refundable in case it is not approved.
