It looks like the Detroit-Windsor Amazon bid was a bust.

Toronto is the only Canadian city on Amazon Inc.'s short list of 20 candidates for a second North American headquarters.

The e-commerce giant received 238 applications for the opportunity and says narrowing it down to 20 was very tough.

The other 19 locations it will consider are all in the U.S. and include New York City, Chicago, Los Angeles, Denver and Nashville.

Windsor was offering Amazon an incentive package valued at US$106 million in a joint bid with Detroit to lure the tech giant.

Windsor mayor Drew Dilkens tells CTV News he is eager to hear back from Amazon on ways to improve their bid for future proposals.

"We will literally take this document, this proposal, we can substitute Amazon, with any other company who is interested in a one campus two county proposal and go after them,” says Dilkens.

Detroit Mayor Mike Duggan released a statement this morning about the disappointing news, but thanked Windsor Mayor Drew Dilkens for his co-operation.

"We would have loved to have made it into the next round for Amazon's second headquarters but everyone here is incredibly proud of the proposal we submitted. It showed a clear vision for the future of our city and brought out the very best of our city and our region.

I want to thank Dan Gilbert, the Governor, County Executives, Windsor Mayor Drew Dilkens and the entire bid team for an extraordinary effort in a short period of time. We learned a great deal from this process and it was a very valuable experience. We're going to keep building on the progress we’ve made and keep pursuing major developments. I expect that the lessons we learned in the Amazon process will help make us more successful on a number of other major potential investments that we are currently pursuing.

We're going right back to work today to work on those other projects."

Amazon says it plans to choose the location later this year after diving deeper into the proposals from its top cities.

An Amazon spokesperson says the process taught the company about several new communities across North America that it will consider as locations for future infrastructure investment and job creation.

The company plans to invest more than $5 billion into the forthcoming headquarters and hire 50,000 highly paid employees in the city housing it.
