That's correct. You can submit your old medical exam results as part of your application for permanent residence in Canada. However, it is up to the visa officer to decide whether or not to accept them. If the visa officer decides that your old medical results are not sufficient, they may request that you undergo a new medical exam.
There are a few factors that the visa officer will consider when making their decision, including:
- The date of your old medical exam.
- The results of your old medical exam.
- Any changes in your health since your old medical exam.
If you are concerned about whether or not your old medical results will be accepted, you can contact the visa office for more information.
I hope this helps!
