Angular 4 and route protection with my Auth Guard

I am creating an application in Angular 4 but I do not know what is happening that my router is protected with my Guard but it does not redirect me to the login page when I try to enter a forbidden URL, it could indicate me that I am doing wrong

I leave the code

auth-guard.services.ts

import { Injectable } from '@angular/core';
import { CanActivate, Router, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router'; 
import { UserService } from './user.service';

@Injectable()
export class AuthGuardService implements CanActivate {

  constructor(private userService : UserService, private router: Router) { }

  canActivate(route: ActivatedRouteSnapshot, state : RouterStateSnapshot) {

    window.alert(this.userService.isValid());
    if(this.userService.isValid()!=true) {
      this.router.navigate(['login']);
      window.alert("No puedes ver esta pagina");
      return false;
    } 

    return true;
  }

}

user.service.ts

import { Injectable } from '@angular/core';

@Injectable()
export class UserService {

  constructor() { }

  isValid(): boolean {
    return false;
  }

}

app.modules.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { AuthGuardService } from './auth-guard.service';
import { UserService } from './user.service';
