I'm planning to go in Canada. But I'm vaccinated...

We would like to inform you that regarding traveling to Canada, which is not acknowledged by the Canadian government, this is a matter for the Canadian Embassy alone, and it is the decision-maker.
 As long as the Sputnik vaccine is taken, the first and second, it may be impossible to get the Pfizer vaccine.
Therefore, we recommend that you refer to the embassy and inquire about the situation and explain the situation to them for the purposes of granting you permission to travel.
This is in general and if you have any legal inquiries you are most welcome 

The assessment for this matter is for the embassy. It is possible to review and obtain legal guidance according to the approved protocol
