Disagreement over U.S. President Obama’s healthcare law has led to the first government shutdown in 17 years – so how will it affect Canadians?

The severity of the international impact is entirely dependent on how long the shutdown lasts, which could be anywhere from a number of hours to days. The last U.S. government shutdown happened 17 years ago and lasted 27 days.

Former deputy prime minister John Manley described the threat of a new U.S. federal shutdown to Power & Politics host Evan Solomon as “very grave.”

Canadians, along with other tourists, visiting the U.S. would likely be the first to feel the first ripple effect. All visitors would be barred from national monuments and parks after “non-essential” employees who staff these sites are asked to stay at home.

“This is a reminder that while Canada’s economy remains strong, we are still vulnerable to uncertainties outside of our borders, especially in the U.S. and Europe,” Finance Minister Jim Flaherty said in a statement Monday.

In terms of finances, Canadian treasury bills could experience an influx of U.S. capital as investors look for somewhere safe to keep their money, speculates Nomura Securities foreign exchange strategist Charles St-Arnaud.

Some ways Canadians could be affected during the U.S. government shutdown:

  • National Parks: No Access

    Tough break if you're in the U.S. looking to visit one of the 59 protected national parks as visitor centre employees are told to stay at home.

  • National Monuments: No Access

    Another raw deal for Canuck tourists who wish to visit the Statue of Liberty and other U.S. national monuments. Employees here are deemed <a href="http://www.huffingtonpost.com/2013/09/27/government-shutdown-2013_n_4003465.html" target="_blank">"nonessential" </a> and sites will be unstaffed, closed.

  • Travel Through U.S. Airports: Normal, Some Caution

    Security workers, customs agents, and border patrol are deemed "essential," so normal service is expected (though some airports have warned passengers to expect delays).

  • Border Services: Normal

    Because border patrol and customs agents are deemed "essential" by the U.S. government, services and border wait times should be normal.

  • U.S. Visa, Passport Applications: Normal

    Canadians applying for U.S. work visas, passports should not expect major delays as fees are collected for these services. Green card applications will also continue to be processed. Note: During the last U.S. government shutdown 17 years ago, <a href="http://usnews.nbcnews.com/_news/2013/09/29/20745618-a-government-shutdown-what-could-it-look-like?lite" target="_blank">20,000-30,000 visas and nearly 200,000 passport applications</a> went unprocessed, NBC News reports.

  • Panda Cam: Shut Down

    Bad news for Canadians fans of the National Zoo's panda cam. The <a href="http://www.huffingtonpost.com/2013/09/30/panda-cam-government-shutdown_n_4017036.html?ir=Canada" target="_blank">zoo</a> confirmed Monday should a spending bill not be passed by congress, its panda cameras will be turned off. No pressure, right <a href="http://www.huffingtonpost.ca/2013/05/18/toronto-zoo-pandas_n_3298470.html" target="_blank">Da Mao and Er Shun</a>?

  • Financial Markets: Uncertain

    Given the two country's intertwined economies, the impacts of the U.S. government shutdown would be felt first in Canada's financial markets but are entirely dependent on how long it lasts.

  • Canadians With U.S.-Government Income Stream: Situational

    Canadians with American spouses, partners working in "nonessential" government jobs could be put in a financial pinch if paycheques are halted during the shutdown. More than a third of U.S. federal employees deemed "nonessential" will be asked to<a href="http://www.huffingtonpost.com/2013/09/27/government-shutdown-furloughs_n_4001847.html" target="_blank"> stay at home without pay</a>, while "essential" employees are expected to work without a paycheque.

  • Dollar Value: Outcome Foggy

    Some analysts predict the U.S. shutdown will be a positive for the Canadian dollar, depending how long it lasts. New York-based Nomura Securities foreign-exchange strategist Charles St-Arnaud, speculates U.S. capital could flow into Canadian treasury bills as investors look for a safe place to hold their cash.

  • Loans For Some U.S. Homes: Halted

    Qualified Canadians shopping in the U.S. for real estate with low-to-medium incomes will not be issued government-backed loans. New loan applications will not be processed while the government is in shutdown.
