Going to Toronto in August, I saw the weather forecast that the temperature was not high. Do I need sun protection? Was the ultraviolet light strong at that time?

The sun in Toronto is much more violent than that in China. Be sure to protect yourself from the sun when you go out. I went fishing the other day. It was supposed to be cloudy, but the sun came out when I arrived. About three hours, all the skin was sunburned.

If you are just shopping, you don't have to take the bus. But when you go out to watch a performance, you need to bring it when you play outdoors.
