That puffy announcement also confirms they have essentially abandoned any significant transportation link between Exhibition Station and OP. Doug Ford will drive up in his Escalade, cut the ribbon on the sidewalk, and that's it. Hence the huge garage.
Maybe someone else can find the clip but I seem to recall that at one of thre press conferences, El Prremier talked fondly about how, like so many of us, he has fond memories of pulling up to Ontario Place in the family boat.
So I don't think it's fair to assume he'll definitely be driving up in an Escalade.
