Amazon.com is scouting North American cities for a second company headquarters, where it plans to hire as many as 50,000 full-time workers, the tech giant announced on Thursday.

The Seattle-based company says it plans to invest $5 billion in construction and operation of the new location, which it is calling Amazon HQ2.

โ€œWe expect HQ2 to be a full equal to our Seattle headquarters,โ€ Jeff Bezos, founder and chief executive of Amazon, said in a statement. โ€œAmazon HQ2 will bring billions of dollars in up-front and ongoing investments, and tens of thousands of high-paying jobs. Weโ€™re excited to find a second home.โ€

Amazon is seeking proposals from local, state and provincial government leaders, and says it is focusing on metropolitan areas with more than 1 million people. It is also looking for areas that can attract and retain technical workers and โ€œa stable and business-friendly environment.โ€ The company plans to make a decision next year.

News of the search has unleashed a wave of speculation about where the worldโ€™s largest online retailer could set up shop. But experts say the companyโ€™s decision is likely to be as much about politics as it is about logistics and incentives. Bezos has been a vocal opponent of the Trump administrationโ€™s immigration bans, and earlier this week was among hundreds of tech leaders who urged the president to reconsider his stance on the โ€œdreamersโ€ immigration program.

โ€œThe fact that Amazon is even considering Canada and Mexico shows how important politics has become in the site-selection process,โ€ said John Boyd, a Princeton, N.J.-based location consultant whose clients include Boeing, Chevron and JPMorgan Chase. โ€œThis is a high-profile search, and Amazon has an incredible amount of wherewithal to influence state and federal legislation.โ€

Toronto, where it is easier to hire foreign workers than in the United States, could be a top contender for Amazonโ€™s new headquarters, according to Boyd. (Other areas he thinks are likely: New Jersey, south Florida, northern Virginia, Atlanta.)
