Within the canActivate function the ActivatedRouteSnapshot and the RouterStateSnapshot is passed through as arguments:

@Injectable()
export class HasPermissionService implements CanActivate {

   private permissions = [];

   constructor(private _core: CoreService) { 
     this.permissions = this._core.getPermission();
   } 

   canActivate(
      route: ActivatedRouteSnapshot,
      state: RouterStateSnapshot
    ): Observable<boolean>|Promise<boolean>|boolean {
       //check here
    }
}

You should start there to look at which route is being activated. The URL segments matched by this route are inside the route.url
