Kalim Khan has been a cab driver in Saskatoon for the past four years. During this time he says he has returned countless items to the absent minded and often inebriated travelers who rely on him for a ride.

This is why Khan insists the events that followed a particular cab fare last month are nothing special.

''I found your bag, with the money and the IDs and it is safe and I will hold it until you get back,' - Kalim Khan

Khan drove a local family to Saskatoon's airport in December 2013. The family was going on vacation to Mexico.

Khan says that just like any other group he drives to the airport, he made sure to remind them all to check and make sure they had their passports and IDs before they left the family's home.

With the confidence that everyone had what they needed to travel, Khan drove the group to Saskatoon's airport, wished them good luck and continued to work his 12-hour night shift for Radio Cabs.

It wasn't until the end of the shift when he was cleaning his car that he noticed a clear, plastic bag filled with $1000 cash and personal documents.

Khan says he never even though about taking the money for himself, but only of how to get it back to the family in time for their trip.

"I decided, OK, in the dispatch call there was a number for [the family]," Khan said. "I tried to call that number and it said they would come back on the eighth of January. I [left] a message [saying] 'I found your bag, with the money and the IDs and it is safe and I will hold it until you get back.'"

When the family returned from their holiday, Khan says they were overjoyed when they learned he had their money.

"The happiness and the joy on his face. You know, it was glowing on his face. You know really, it's not just the money. It is believing in humanity," Khan explained.

Khan said he did what 99 per cent of Saskatoon cab drivers would have done.

"I have many times returned wallets, iPhones, Samsung Galaxy, Nokias, found in my cab, because drunk people sometimes lose them in the cab," Khan said. 

Khan personally drove his cab over to the family's house to return the bag of money. In thanks, they gave him $150 as a reward.

However, Khan says he doesn't plan to spend the cash. Instead he told CBC News he plans to frame the bills, so he can always be reminded of the happiness his good deed brought.
