I live in south-eastern Canada today it was 35C which is something I've never seen here. And the humidity at one point was 90% which is typical since I am on an island. Thankfully it went to about 70%.

I felt tired it wears you out even 35C is OK but any humidity over 60% is terrible. My entire childhood up until ten years ago a 30C day here was a very hot day that came maybe once per summer but most years never.
