Visa Stamping from Canada/ Mexico

Guys, if you don't have PR or Citizenship of Canada , please don't book appointments. I have seen many posts where people were planning to get stamped without PR, they had visitor visa or wanted to get one or they were asking : is quarantine only if they come through US. The border is de facto closed for visitors and there is no clear idea when it will open. Moreover, they are only honoring emergency appointments at the moment for visas and rescheduling regular appointments atleast those of november. It is understandable that it is difficult with so many uncertainties and need for stamping, but scheduling and canceling will create a mess. There are those in Canada who can attend an appointment but it maybe blocked by someone who cannot enter the country. Sorry , not trying to be negative, just laying down the facts
