Canada is a rich country, but still (it) has many poor people in it.
Can we omit the pronout "it" or its use is compulsory here?
Which is better? to use it or not.
But you can omit it.
I think you should tell aous02 that it can be omitted, ellipsed, because from the discourse it is clear who or what is the subject of 'has many poor people.' If that were not so, you would have to reference Canada specifically, and that it is not wrong to use it.
