SASKATOON - Gov. Gen. David Johnston says it isn't his place to interfere in the Harper Conservative government's plan to eliminate the Canadian Wheat Board monopoly despite a plebiscite that suggest farmers don't want to do that.

Johnston was answering questions Tuesday at the University of Saskatchewan.

He says 150 years ago, the governor general may have had a theoretical right to veto a bill and did so from time to time.

But Johnston said that day is gone.

Just over 60 per cent of Prairie wheat growers and 51 per cent of barley growers voted in favour of maintaining the monopoly.

Fifty-five per cent of eligible wheat producers and 47 per cent of barley growers participated in the vote.
