Big brown wallet with some design on it

My husband, myself & our children went shopping at fresh Co today (july 12, 2014) at around 1:30/ 2pm. On Tecumseh & Rivard. My husband was holding my wallet counting what money I had left for me. From there my husband figures he either placed it in the shopping cart while he put our son into the van or it fell out of the diaper bag as he was walking from the cart return back to the car.

It could have also fallen out when we stopped at the windsor airport near the windsor flying club doors. When we were showing our son the planes

This wallet has all my Id as well as my kids ID (sin # & health card) as well as some money (I know exactly how much but that's not the most important)
It would be greatly appreciated if it has been found that it be returned both myself & my son have constant health issues.

If the wallet is returned with everything inside there is a huge reward !
