  This will activate your Canvas on the first airtap and destroy it on the second airtap:

  using UnityEngine;
  using HoloToolkit.Unity.InputModule;
  
  public class CanvasManager : MonoBehaviour, IInputClickHandler
  {
      public GameObject canvas;
  
      bool destroy = false;
  
      private void Start()
      {
          InputManager.Instance.AddGlobalListener(gameObject);
      }
  
      public void OnInputClicked(InputClickedEventData eventData)
      {
          if (!destroy)
          {
              canvas.SetActive(true);
              destroy = true;
          }
          else
          {
              Destroy(canvas);
              //Also destroy this script. We dont need it anymore since the canvas is destroyed!
              Destroy(this);
          }
      }
  }
  

  Just attach this script to an empty gameobject and assign your canvas

  Thanks for getting back to me! You are a Ninja!
  Maybe I am doing something wrong but I implemented your script and the only thing that is happening is my canvas (Canvas1) is closing "if" I have it active within the Hierarchy.
  If I click on my gameObject (Monkey1), that your script is assigned to after that, nothing happens.
  The way my hierarchy is set up is that my canvas (Canvas1) is a child of the gameObject (Monkey1). Here is my code:

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  using HoloToolkit.Unity.InputModule;

  public class InteractibleManager: MonoBehaviour, IInputClickHandler
  {
      public GameObject Canvas1;
  
      bool destroy = false;
  
      private void Start()
      {
          InputManager.Instance.AddGlobalListener(gameObject);
      }
  
      public void OnInputClicked(InputClickedEventData eventData)
      {
          if (!destroy)
          {
          Canvas1.SetActive(true);
          destroy = true;
          }
          else
          {
          Destroy(Canvas1);
          //Also destroy this script. We dont need it anymore since the canvas is destroyed!
          Destroy(this);
          }
      }
  }
  

  I was hoping to have the canvas non active until the gameObject is clicked on and then destroyed once it is clicked on again. This could happen over and over sort of like a menu.
  I really appreciate your help in this!!!

  Oh okey so basically you want a menu which will open when clicking your gameobject (Monkey1).
  If so then we dont need the globalListener since you have the script attached to a gameobject which you click.

  Also we dont want to destroy the canvas, if its destroyed we cant re-activate it, because its gone. So lets set it active and inactive. I guess thats the behaviour you want.

  public class InteractibleManager: MonoBehaviour, IInputClickHandler
  {
      public GameObject Canvas1;
  
      bool active = false;
  
      public void OnInputClicked(InputClickedEventData eventData)
      {
          if (!active)
          {
              Canvas1.SetActive(true);
              destroy = true;
          }
          else
          {
              Canvas1.SetActive(false);
              active = false;
          }
      }
  }
