It has been tried and failed before.... few different variations.
There are a few usual problems. Port Weller to Ontario Place doesn't get commuters to ideal locations. Next is the cost, not stated but this will be a big factor. Finally, risk of it lasting, if you rely on this will it really run practically everyday (weather) and will it be in business next year?
On the first point, Ontario Place is not really downtown and a decent hike to transit. Going the other way Port Weller doesn't do much for tourists but there is limited options on that end. Docking in the harbour on the TO end would be better....
Cost, we do not know.... but it has to be comparable to GO or car which it may be... BUT unless you live in Port Weller you have to have a car.
On the last point car or GO have their own issues but it needs to be at least as reliable as employers don't like, sorry boat was down today on a regular basis... There is a long runway before people trust it enough to make it the main option (or say move to Niagara).
The local community paper just carried the article as well and I mulled around the logistics.
The only ones that could benefit from it on a regular basis is St Catherine area home owners working in Toronto. Drive, walk or bicycle to the Port Weller parking lot, take the hovercraft, arrive at Ontario Place and find your way to work, assuming downtown.
The lure is a nice house in a modern city at half the price of Toronto. A cursory glance at prices says you could save $750 K.
The economics of running the craft raise red flags.
1) $60 round trip for 180 people = $10800 per round trip BUT if it's only shipping people to TO in the morning and shipping them back in the PM it means the thing is sitting idle all day. Multiple runs are needed but that means going back and forth empty to drop loads. I hear money toilets flushing.
2) Assume people leaving Port Weller between 6:00 AM and 9:00 AM with each craft taking an hour round trip. It will make $32400 before expenses. How many crew members are there and what qualifications do they need?
The salaries will have to compensate for a split shift scenario because it's unlikely the craft will be busy all day. Eight hour day, 6-9 AM and 4-7 PM with dead time in between. For reasons of practicality the crew will have to be based in St Catherines.
Summer weekends could see traffic go the other way if Torontonians wanted to hit Dalhousie or the wineries on weekends. Local entrepreneurs would have to make that happen with buses etc.
2) Travel time by train from St Catherines to Union Station is 1:41 for IIRC $20 each way.
Ignore the travel time from home to the Port Weller parking lot. The lake crossing is stated as 30 minutes but it's unlikely the turn around time, people folding their newspapers, putting away their laptops, putting on coats etc is 30 minutes.
Arriving at Ontario Place means a shuttle bus or a 20 minute walk to TTC service. Total time 36 Minutes Toronto travel to Union Station.
Actual time travelling may be 1:06 but the loading and off loading will likely push it to 1:30 point to point. Obviously a shuttle from Ontario Place to Union is needed and will reduce times but be on top of the $60 round trip fare.
Owning in St Catherines and working in TO with similar house could save $3000 or so a month, ignoring qualifications. Travel costs could eat up half of that. Two people doing it could be a only a break even. WFH or even partial WFH could be a game changer.
IMO the $60 trip is a joke. Consider the capital outlay for the craft, the docking and parking areas, crew costs and maintenance.
Pipe dream, but if it ever gets off the water I'll probably go for a joy ride before it closes.
