var canvasTiles = L.tileLayer.canvas();

canvasTiles.drawTile = function(canvas, tilePoint, zoom) {
	var ctx = canvas.getContext('2d');
      ctx.fillText(tilePoint.toString(), 50, 50);
      ctx.globalAlpha = 0.2;
      ctx.fillStyle = '#000';
      ctx.fillRect(10, 10, 246, 246);
};

canvasTiles.addTo(map);
