new Date(year, month, date) variant will have the date in current system time zone.

The reason you comparison doesn't return any results is when you pass the date in your local system zone , the meteor does a conversion from local datetime to UTC datetime as Mongo DB datetimes are in UTC time. So your input date changes from Sat Nov 19 2016 00:00:00 GMT+1100 (AEDT) to Fri Nov 18, 2016 01:00:00 UTC.

Considering user inputs date as UTC. You'll just need to parse the date explicitly as UTC.

Try

new Date(Date.UTC(2016, 11, 19, 0, 0, 0, 0)

and pass this to the query.
