Both the Hilton Hotel and the Tannery Building have anticipated opening dates in 2018, so I imagine that construction will have to begin in the next couple of months to keep a proper timeline.
I'm pretty confident about the Hilton Hotel, because they have already announced the brand affiliation, and I imagine they want the hotel open at roughly the same time as the events centre.
I'm a little less confident on the Tannery. It's an apartment building rather than a condo development, so they aren't dependent on pre-selling units, but still, they will have to have financing in place, and there are a lot of rental units in the city coming on stream in the next 12 months or so. Obtaining financing may be difficult.
