There are serious issues here, as there are in many other neighbourhoods - but I disagree with the assertion that its unliveable.
This neighbourhood has just been non-stop development in recent years, and I think that's contributed to the difficulties in living here more than it being a tourist locale. At the same time, I have to wonder if the reason why folks choose to steer clear is because they're drivers. Personally, I don't drive, so I don't know the frustration of spending 45min trying to get into my garage because of a slew of tourists and buses.
We've definitely been let down by the city in the endless construction, and lack of traffic management on Mill St. And speaking of Mill St., we were promised a parkette beside the Data Centre during planning, but have yet to see it be more than a car lot for the dealership on Front.
But for the most part, I walk to No Frills, Loblaws, St. Lawrence Market, Metro and T&T. I take the (crowded) King streetcar, or either the 121 or 65 bus. All the delivery services get me food and parcels at my door. I enjoy a good walk over to Corktown Commons, a cycle up to Cherry Beach, or a work out at the nearby YMCA. I've got a ton of options for dinner if I need to entertain, and I like heading down to check out ArtFest, or the Leslieville Flea (winter) or whatever other event is going on downstairs.
And that's before we get East Harbour, the port lands and waterfront development, Google/Alphabet's city project, Daniel's Waterfront and the Sugar Beach Innovation Centre, which hopefully will provide walkable employment opportunities for the people who live here.
Would it help to see that big parking lot at Front/Trinity/Cherry dug down a few levels for parking, then build a four storey retail complex (anchored by a grocery store) with offices on top... totally.
But is the neighbourhood "unliveable". Nah. Not by a long shot.
