Answer 1

You can return the observable as Observable

canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
    return this.loginService.isAuthenticated()
        .map(status => {
            console.log(status);
            this.authenticated = status;
            return true;
        }).catch((err) => {
            console.log(err);
            return Observable.of(false);
        });
}
