"Ionic 3: Utilizing the If Statement within the subscribe() Function for Increased Results

I added an if conditional in my subscribe() function where I used return; to break if it meets the condition. However, instead of breaking the entire big function, it only breaks the subscribe() function and continues to execute the navCtrl.push line. How can I fix this issue?

grabInfo(){
    this.ServiceProvider.grabRAW(this.email).subscribe(data => {
        this.infoList = data.data;
        if (this.infoList == null){
          loader.dismiss();
          toast.present();
          return;}
        //console.log(this.infoList);
        this.navCtrl.push(ResultPage,{infoList: this.infoList});
      }
    );
  }

          this.navCtrl.push(ResultPage,{infoList: this.informationList})}
        else{
          loader.dismiss();
          toast.present();
