Cross-Border Workers Left Behind: How Treaties Fail Amid Surging Labor Shortages

Cross-border workers forfeit thousands in pension benefits due to obscure totalization rules, as seen in U.S.-Canada cases. Meanwhile, aggressive immigration enforcement has stripped 1.2 million foreign-born workers from the U.S. labor force, hammering construction, agriculture and hospitality with acute shortages and rising prices. Treaties help the informed but cannot offset systemic labor gaps.
Cross-Border Workers Left Behind: How Treaties Fail Amid Surging Labor Shortages
Written by John Marshall

A 65-year-old man spent eight years in Toronto during his 30s. He paid into Canada’s pension system. Then he returned south and logged 32 years at a U.S. manufacturer. Now retired, he figured those Canadian years vanished. “I guess those years don’t count.”

They do. But only because of a 1984 treaty few have heard of. The difference adds roughly $449 a month for life. Real money. Yet thousands of cross-border workers never claim it. They miss out on benefits they earned. And this quiet loss sits against a louder crisis: entire industries now scramble for workers as immigration policies tighten.

The U.S.-Canada Social Security Totalization Agreement pools credits from both countries. It lets people qualify even if they fall short of the usual 10-year minimum in one place. Service Canada still requires at least one valid contribution. Eight years clears that bar. The treaty treats U.S. work history as proof of workforce attachment. Claims move forward. But Canada pays only on actual contributions made north of the border. No windfall. Just a proportional slice. In the example, that slice equals about $620 CAD monthly, or $449 USD at current rates. Yahoo Finance laid out the scenario in detail.

Forum threads from snowbirds, expats and commuters repeat the same mistake. People assume foreign credits disappear. They file separately. They leave money on the table. Retirees should apply through the Social Security Administration for a totalization claim. They can choose claiming ages independently too. U.S. delayed retirement credits and Canadian adjustment factors work differently. Many maximize lifetime income by taking Canada Pension Plan at 65 and holding U.S. Social Security until 70.

But the treaty’s limits show up fast. It unlocks eligibility. It does not create new benefits from thin air. Eight years yields eight years’ worth. Workers with shorter stints or spotty records still fall through cracks. And the agreement covers only two nations. Similar deals exist with other countries. Yet awareness stays low. Bureaucratic hurdles remain high.

Policy Gaps Meet a Workforce in Retreat

That individual story now collides with broader forces. U.S. immigration enforcement has removed hundreds of thousands from the labor force since early 2025. Foreign-born workers make up one-fifth of the total. Their departure has cut deep. PBS reported as many as 1.2 million foreign-born workers left by mid-2025. Construction, agriculture, hospitality and manufacturing feel it first.

One construction trade group says the U.S. must add 349,000 workers in 2026 just to meet demand. Immigrant labor fills 35 percent of those jobs. ICE raids trigger immediate drops. A National Bureau of Economic Research paper found employment among likely undocumented immigrants fell 4 percent in raided areas. Construction saw a 7.5 percent drop. Fortune connected the dots. Half a contractor’s crew stopped showing up after a raid 230 miles away. Fear travels far.

Agriculture tells a similar tale. Foreign-born farmworkers account for 68 percent of the workforce. About 42 percent lack authorization. The Labor Department warned in 2025 that halting new inflows risks “supply shock-induced food shortages.” Unemployed Americans do not rush to fill 12-hour shifts in extreme heat. Food prices have already begun to reflect the squeeze. Forbes called it the real immigration tragedy. Shrinking the workforce at the worst possible time. Social Security funding feels the strain too. Fewer workers support more retirees.

But. The same policies that cut unauthorized entries also revoked work authorization for over 500,000 people with temporary status. FWD.us modeled the outcome. Food, beverage and tobacco prices could rise 14.5 percent by 2028. Restaurants lost 145,000 immigrant workers on average through August 2025 compared with the year before. Construction shed 127,000. Landscaping dropped 43,000. Stateline tracked the losses across sectors. One landscaping firm forfeited $50,000 in contracts when crews vanished amid raid rumors.

Associated General Contractors of America surveyed its members. Ninety-two percent struggle to fill open positions. Workforce shortages now rank as the top cause of project delays. Twenty-eight percent report direct or indirect impact from immigration enforcement. Some saw agents at job sites. Others lost subcontractors’ crews. AGC called for more education funding and new legal pathways for workers to enter the country.

Europe faces parallel pressures. Truck driving shortages grow acute. Companies recruit migrants to keep logistics moving. Yet many drivers encounter debt, dependency and poor conditions in cross-border chains. InfoMigrants reported the trend just days ago. Poland hit a record 1.29 million foreign workers by late 2025. Demographic decline leaves no choice. Similar stories emerge from retail, health care and data centers across the continent.

So the cross-border worker who misses a few hundred dollars monthly represents a symptom. Systems built for steady flows now confront sudden stops. Totalization agreements help those who know they exist. They cannot replace the steady supply of new labor that industries counted on. Claims processing stays slow. Outreach stays limited. Retirees in their 60s and 70s rarely scour government websites for obscure treaties.

Recent data from Indeed shows foreign job-seeker interest in U.S. positions at a six-year low. Employer willingness to sponsor visas has shifted too. Health care, construction and manufacturing post the biggest gaps. These fields needed workers before enforcement ramped up. Now the gaps widen. Hiring Lab captured the decline in May 2026.

Business groups have noticed. The U.S. Chamber of Commerce argues the border may feel more secure but the economy does not. It calls for updated visa programs that match current needs. Essential non-agricultural workers lack sufficient legal channels. H-2B caps rose recently, yet demand outruns supply. Construction faces a “workforce shortage cliff” made worse by data center growth and enforcement. Associated Builders and Contractors predicts 349,000 net new workers needed in 2026, then 456,000 more the following year.

Advocates push targeted fixes. Expand TN visas for professionals from Mexico and Canada. Adjust H-2A and H-2B rules to reduce red tape. Create pathways that let employers sponsor workers without years of uncertainty. Yet political momentum runs the other way. Deportations continue. Temporary protections expire. The foreign-born population fell from 53.3 million in January 2025 to about 51.9 million by June. That drop alone removed hundreds of thousands of consumers and taxpayers.

Economists warn of slower growth, higher prices and strained public finances. One habit does not fix structural gaps. Doubling down on domestic training helps at the margin. It cannot conjure enough bodies for fields Americans have long avoided at prevailing wages and conditions. The 65-year-old who almost forfeited his Canadian pension learned the hard way. Systems reward those who know the rules. Most never learn them.

Cross-border arrangements once promised smoother lives. They papered over differences in pension systems and work histories. Today those same arrangements look inadequate. Labor markets on both sides of borders tighten. Retirees lose benefits they earned. Employers lose workers they need. And the gap between policy intent and economic reality grows wider still.
