While Donald Trump bragged at the United Nations yesterday about U.S. economic growth, Wednesday brought some bad news for America’s would-be “jobs” president: highly skilled tech employees are absconding to Canada. Start-ups in the Canadian tech hub of Toronto say that they’ve been receiving “steady, double-digit increases” in job applications from the United States since the 2016 election, Axios reports. Many appear to be concerned about the president’s crackdown on visas and immigration, and are looking north for more options.

The exodus is not unexpected. Earlier this year, Trump signed an executive order initiating a government review that is expected to make it harder for companies to obtain H-1B visas for foreign workers. As a result, other countries began making plays for tech talent that, under any other administration, would likely be staying stateside. “We’re seeing a reverse brain drain for the first time. There are highly talented Canadians—educated in Canada or the U.S.—who are now seeking to come back home,” biotech start-up Cyclica’s C.E.O., Naheed Kurji, told Axios. “There has been a significant spike in those conversations. Some of the most highly sought-after talent are asking, ‘What positions do you know of in Toronto?’ These are leaders in their industries in New York, San Francisco, Los Angeles, and Chicago.”

Toronto already offered a compelling alternative to Silicon Valley, hosting a 1.5 million-square-foot start-up incubator, the MaRS Discovery District, as well as offices for IBM, Autodesk, Merck, and some 150 start-ups across a variety of sectors. For many Trump-averse engineers and scientists, it seems, the president’s politics decisively changed the calculus in Toronto’s favor. “I’ve been in tech for over 20 years in Canada and in Silicon Valley, too. I’ve never seen candidates from the U.S. apply for Canadian positions from places like Silicon Valley,” Roy Pereira, the C.E.O. of enterprise chatbot start-up Zoom.ai, said. He added that the U.S. applicants he’d met with seemed “concerned just because of the directionality that the country was taking.”

Several countries have made overtures to American S.T.E.M. workers disenchanted with Trump. Earlier this year, Canada launched a new visa program called Global Skills Strategy to help siphon Silicon Valley’s brain drain. Global Skills Strategy makes it easier for companies to recruit highly skilled foreign workers; instead of waiting for months for a work visa like one might have to do in the U.S., the new Canadian visa program allows employees to be approved for a visa in just two weeks. A number of countries, including France and China, haven’t been shy about their desire to poach top American talent, either. This summer, French President Emmanuel Macron launched a Web site aimed at luring foreign scientists with sizable grants.

The animosity toward Trump in Silicon Valley, meanwhile, continues to build. This week, the tech industry’s D.C.-based lobbying shop, the National Venture Capital Association, sued the Trump administration after it delayed putting into effect the International Entrepreneur Rule, which started under former president Barack Obama to let experienced entrepreneurs from other countries come to the U.S. for 30 months without a visa while trying to build a company. Lyft co-founders John Zimmer and Logan Green told me that they will do everything they can to protect any “Dreamers”—undocumented employees who came to the U.S. as children—working for their company. And tech firms throughout the Bay Area continue to put out statements denouncing the president for what many perceive as racially divisive and inflammatory rhetoric. Whether that will be enough to encourage uncertain engineers and computer scientists to stay put, when universal health care and cheap higher education beckon just over the northern border, remains to be seen.
