Toronto to Singapore, what's the best place to stop over
I used to transit in Los Angeles, Dubai, Shanghai, Beijing, . With COVID-19, looks that options are limited to Tokyo, Seoul, Taipei, Hong Kong and Doha. (I am not considering any European cities, as Europe is full of COVID-19).
What is the best choice and which country does not require quarantine? I have heard a lot of violent stories about Hong Kong and Taipei from my Asian colleagues; with personal security as my first priority, among Tokyo, Seoul and Doha, what would be the best place to transit for a day or two?
Time would be in September.
