JavaFX root.getChildren not working?

Probably to complicated a question for treehouse, but im wondering why i suddenly cant use the .getChildren() from the root element. Im basically trying to add a canvis to the root, and i would do it like i always add stuff to the root that is: root.getChildren().add(whatever), but since the root for whatever reason dosent have a getChildren() method i cant do that. If anyone out there knows a bit about java, help would be greatly appreciated!

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.canvas.Canvas;
import javafx.scene.canvas.GraphicsContext;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 300, 275));

        // Create canvas (Thing that you can draw on)
        Canvas canvas = new Canvas(300,275);
        // Add canvas to root 
        root.getChildren.add(canvas) // FOR SOME REASON THIS DOES NOT WORK!

        // Set Graphicscontect ie. the thing used to draw on a canvas
        GraphicsContext gc = canvas.getGraphicsContext2D();

        // Draw hello world and a globe
        gc.setFill(Color.RED);
        gc.setStroke(Color.BLACK);
        gc.setLineWidth(2);
        Font font = Font.font("Times New Roman", FontWeight.BOLD, 48);
        gc.fillText("Hello World!", 60, 50);
        gc.strokeText("Hello World", 60, 50);

        // Show stage
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

Hey behar. I wish I could tell you what is wrong, but my Java is rusty and I've never used JavaFX, so I'm more lost then you ?. Hope you get it figured out!
