ionViewCanEnter still executing page load

I have a common set of code that runs on ionViewCanEnter, which checks if a user is logged in before displaying secure pages. This seems to work...on the surface.

When a user isn't logged in, there is a split second where the page is seen before it navigates to the non-authenticated page. I can also see that the page load does get executed (ionViewDidEnter does fire). The page access is blocked...eventually. How can I prevent the page load from executing, and prevent the page from being displayed for a split second? Here's my common implementation of ionViewCanEnter.

ionViewCanEnter() {
    this.loggingService.debug("securePage: ionViewCanEnter");
    this.auth.hasLoggedIn().then((loggedIn) => {
        if (!loggedIn) {
            this.loggingService.error("Blocked a page view - user not logged in");
            this.events.publish(Constants.EVENT_LOGOUT, true);
            return false;
        }

        //Good to go
        return true;
    }).catch((error) => {
            this.loggingService.error("Secure Page: error getting loggedin status: " ,error);
            this.events.publish(Constants.EVENT_LOGOUT, true);
            return false;
        }
    );
}
