If the standard of living is generally better in the US how is the quality of life better in Canada? Aren’t those the same thing?

I’m mainly curious how standard of living is better in one country compared to the other except quality of life is better in the other.

Is the measurement of each different? I would assume both standard of living equal to quality of life.

You read reports how one country has a better QOL but the other has a better standard of living.
