I believe the answer is:

organisation

I'm a little stuck... Click here to teach me more about this clue!

'order distribution' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'of gas in ontario' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'gas'+'in'+'ontario'='gasinontario'
'gasinontario' anagrammed gives 'ORGANISATION'.

Can you help me to learn more?

(Other definitions for organisation that I've seen before include "Running" , "System" , "concern" , "Systematic approach to tasks" .)
