What if construction workers weren't even allowed on construction sites during quiet hours?

The most frustrating thing about all the construction near me is the frequency with which they wake me up by starting work early. City of Toronto noise bylaws state that construction can't start before 7 a.m. on weekdays and 9 a.m. on Saturdays, but all too often they're out there making noise before that.

The thing is, I think that most of the time when they're making noise too early, they think they're not working yet.  I think they think they're just getting ready to work.

The noise that wakes me up is stuff like gates opening, trucks being backed up, the external elevator operating, and equipment being moved into position (note to construction sites: moving dumpsters around is the single loudest thing you do!).

Then, at 7 on the dot, the noise picks up - big loud whirring machines spring into action, millions of people start hitting things with millions of hammers, etc.  As though they were waiting until 7 to start all this stuff, as though they thought the stuff they were doing before 7 didn't count.

But, nevertheless, the stuff they were doing before 7 still woke me up.

Idea: what if construction workers weren't even allowed on the construction sites before 7? That way they couldn't possibly make noise to wake people up, regardless of whether they think they're working or not.

It would also be easier for by-law officers to enforce (if we ever get by-law officers working outside of business hours - and I'm strongly confident that such an initiative would pay for itself in fines collected if they patrolled the Yonge and Eglinton area between 6 a.m. and 7 a.m.) because if there is any activity or worker presence whatsoever before 7 a.m., that's a violation.  Gate open? Trucks present? Violation.  No debating whether work is being done or not, instead it's a hard and fast "yes or no" question.

On top of that, it would make life easier for workers by disincentivizing the employer from requiring them to report to work obscenely early.  The earliest I was ever woken up by construction was 5:36 a.m. - and this was in the middle of winter!  Imagine how early they had to wake up on a cold winter's morning to get to the construction site in time to wake me up that early!  But if the construction company got fined for workers being on the site early, the employer wouldn't make them come so early, and would in fact order them to "sleep in" another hour and a half so they aren't there before 7.
