N404Cp is operated by a company called Woolpert Inc.
Woolpert Inc is carrying out a statewide - Ohio Statewide Imagery Program (OSIP) - program to capture lidar and hi-res imagery to produce color digital orthoimagery with12-, 6-, 3- and 1.5-inch pixel resolutions and generate consistent digital elevation models (DEM) from lidar.

see >>15182398 they are mapping the state.
These type of survey flights generally happen during periods of stable clear weather to obtain best imagery.
Occasionally survey flights like these are flown after a major storm etc to assess the damage.
I tip my hat at the precision and accuracy of the pilots flying these flights.
Planes will take some time and many flights to cover an area the size of a county and even longer to cover a whole state.
They will concentrate in one area until it is completely covered before moving on to the next area.
Due to needing clear good conditions for the optical imagery they may bounce around the state chasing the best weather conditions.
They may also use several planes each equipped with different equipment in the same area.
As to the Canadian company - there are relatively few companies with the necessary capabilities the customer - Ohio State- needs.
Like most things it generally comes down to who is the lowest bidder or who offers the biggest kick-back.

As an aside I don't think Google maps gets all its imagery from satellites. ;)
