How does passport control work on exit from Heathrow?

Preface: I don’t travel much. And first international trip since pandemic.

I return from UK to my home country Canada yesterday. It occurred to me that aside from check-in desk, there wasn’t anyone who checked my passport.

Was there a step I missed? Or is the UK similar to Canada and doesn’t check passports on exit?
