Based on the code found at Create Multiple Axis from the
Chart.js documentation, this can be done as follows:

const data = [20, 50, 78, 24, 18, 35];
const maxValue = Math.max.apply(null, data);

var myChart = new Chart("myChart", {
  type: 'line',
  data: {
    labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun'],
    datasets: [{
      label: 'My Dataset',
      data: data     
    }]    
  },
  options: {    
    tooltips: {
      mode: 'x',
      callbacks: {
        label: (tooltipItem, data) => {
          var label = data.datasets[tooltipItem.datasetIndex].label || '';
          var percent = Math.round(1000 / maxValue * tooltipItem.yLabel) / 10;
          return label + ' ' + tooltipItem.yLabel + ' (' + percent + '%)';
        }
      }
    },
    scales: {
      yAxes: [{
        type: 'linear',
        ticks: {
          min: 0,
          max: maxValue,
          stepSize: maxValue / 10,
          callback: value => Math.round((100 / maxValue * value)) + '%'     
        }
      }, {
        type: 'linear',
        position: 'right',
        gridLines: {
          display: false
        },
        ticks: {
          min: 0,
          max: maxValue,
          stepSize: 1,
          autoSkip: false,
          callback: value => value % 10 == 0 || value == maxValue ? value : ''
        }
      }]
    }
  }
});
