Angular 2 get current route in guard

I have an AccessGuard class in my project which its work is to determine if user can access to the route or not. I used the router.url to get the current route but the url returns the route before navigation to the new route like I'm in the users route and I click on the candidates route so the url returns users instead of candidates which I want that to validate access to the route
this is my route file:

const routes:Routes = [
{
    path:'',
    component:PanelComponent,
    canActivate:[AuthGuard,AccessGuard],
    canActivateChild:[AuthGuard,AccessGuard],
    children:[
        {
            path:'dashboard',
            component:DashboardComponent
        },
        {
            path:'users',
            component:UsersComponent
        },
        {
            path:'users/:id',
            component:ShowUserComponent
        },
        {
            path:'candidates',
            component:CandidatesComponent
        },
        {
            path:'permissions',
            component:PermissionsComponent
        },
        {
            path:'holidays',
            component:HolidaysComponent
        },
        {
            path:'candidate/:id',
            component:CandidateComponent
        },
        {
            path:'salary/create',
            component:InsertSalaryComponent
        },
        {
            path:'document/create',
            component:InsertDocumentComponent
        },
        {
            path:'leave/create',
            component:InsertLeaveComponent
        }
    ]
}

];

and this is my access guard:

permissions;
currentRoute;
constructor(private authService:AuthService,private router:Router){
    this.permissions = this.authService.getPermissions();
}

canActivate(){
    return this.checkHavePermission();
}

canActivateChild(){
    console.log(this.router.url);
    return this.checkHavePermission();
}

private checkHavePermission(){
    switch (this.router.url) {
        case "/panel/users":
            return this.getPermission('user.view');
        case '/panel/dashboard':
            return true;
        case '/panel/candidates':
            return this.getPermission('candidate.view');
        default:
            return true;
    }
}


getPermission(perm){
    for(var i=0;i<this.permissions.length;i++){
        if(this.permissions[i].name == perm ){
            return true;
        }
    }
    return false;
}
