除了共享边界之外，美国和加拿大近年来在移民方式上似乎没有找到什么共同点。
随着唐纳德·特朗普总统竞相在美国各地设置障碍，贾斯廷·特鲁多总理似乎也同样决心在自己的国家消除这些障碍。
然而，随着加拿大联邦选举的进行，如果特鲁多的保守党竞争对手安德鲁·希尔成功地将总理赶下台，一切都将发生变化。
而特鲁多的自由党设法保持了保守党的微弱领先根据加拿大广播公司公布的平均民调，特鲁多不太可能获得另一个多数政府。
与此同时，不能排除谢尔很快成为加拿大下一任总理的可能性。
如果谢尔在周一投票后宣称获胜，美国人可能很快就会听到一些来自边境北部的过于熟悉的言论，保守党候选人发誓要监督对该国南部边境移民的镇压。
舍尔作为加拿大最年轻的众议院议长创造了历史，本月早些时候公布了他的移民计划。
舍尔计划称加拿大为“地球上最伟大的国家”，指责特鲁多政府未能保护加拿大的价值观。
该计划称，“四年来，他们不仅破坏了上届保守党政府在加强我们移民体系方面取得的进展，还破坏了移民确实对这个国家是一件好事的长期共识。”。"可悲的是，在贾斯廷·特鲁多执政期间，有创纪录数量的加拿大人认为移民应该减少。"
舍尔的政党发誓要“恢复移民系统的公平、秩序和同情心”，并承诺“停止在加拿大和美国边境的非官方入境点非法越境”。
这一努力的一部分将是填补加拿大与美国安全第三国协议中的所谓“漏洞”
根据目前的协议，寻求庇护者如果从美国抵达边境检查站，就不能在加拿大申请保护，反之亦然，因为两者都被视为“安全”国家。
然而，舍尔发誓要结束一项警告，即如果寻求庇护者已经在加拿大，不管他们是如何到达那里的，他们都可以提出移民申请。
保守党候选人的计划坚持认为，“漏洞”鼓励寻求庇护者在指定的入境点之外进入加拿大，并允许他们“跳过队伍，避开队列”
尚不清楚舍尔将如何着手与特朗普谈判寻求收紧加拿大边境的新协议。这位美国领导人不太可能愿意考虑任何可能阻碍他自己移民镇压的协议。
然而，特朗普可能会在舍尔的计划中看到自己计划的一些方面，特别是保守党候选人对加强加拿大南部边境安全的兴趣。他计划再雇佣250名官员加入加拿大边境服务局。
当然，尽管舍尔发誓要在加强边境执法时表现出“同情心”，但他的做法仍将偏离特鲁多的做法，自由党政府计划到2021年每年接纳35万移民，重点是增加加拿大的移民数量。

IF JUSTIN TRUDEAU LOSES CANADIAN ELECTION, U.S. COULD SEE TIGHTENING OF NORTHERN BORDER
Outside of sharing a border, the U.S. and Canada appear to have found little common ground when it comes to their immigration approaches in recent years.
As President Donald Trump has raced to build barriers across the U.S., Prime Minister Justin Trudeau has appeared equally determined to knock them down in his own country.
However, with Canada's federal election underway, all that could be set to change if Trudeau's Conservative rival Andrew Scheer succeeds in his bid to unseat the prime minister.
While Trudeau's Liberal Party has managed to maintain a slight lead on the Conservatives in an average of polling published by the Canadian Broadcasting Corporation, Trudeau is unlikely to secure another majority government.
Meanwhile, the possibility that Scheer could soon be Canada's next Prime Minister cannot be ruled out.
If Scheer does claim victory after Monday's vote, Americans could soon hear some all-too-familiar rhetoric coming from north of the border, with the Conservative candidate vowing to oversee a crackdown on immigration at the country's southern border.
Scheer, who made history as Canada's youngest House Speaker, unveiled his immigration plan earlier this month.
Calling Canada "the greatest country on earth" Scheer's plan accuses the Trudeau administration of failing to protect Canadian values.
"In four years, they have not only undone the progress the previous Conservative government made to strengthen our immigration system—they have managed to undermine the long-standing consensus that immigration is indeed a positive thing for this country," the plan states. "Sadly, under Justin Trudeau, a record-high number of Canadians believe that immigration should be reduced."
Vowing to "restore fairness, order and compassion to the immigration system," Scheer's party has promised to "put an end to illegal border crossings" at unofficial points of entry along the Canada-U.S. border.
Part of that effort would be to close a so-called "loophole" in Canada's Safe-Third Country Agreement with the U.S.
Under the current deal, asylum seekers cannot claim protections in Canada if they arrive at a border checkpoint from the U.S. and vice versa, as both are considered "safe" countries.
However, Scheer has vowed to close one caveat, which does allow asylum seekers to make immigration claims if they are already in Canada, regardless of how they got there.
The Conservative candidate's plan maintains that the "loophole" encourages asylum seekers to cross into Canada outside of designated entry points and allows them to "skip the line and avoid the queue."
What is not clear is how Scheer would go about negotiating a new deal with Trump seeking to tighten Canada's borders. It is unlikely that the U.S. leader would be willing to consider any agreement that could risk hampering his own immigration crackdown.
However, Trump may see aspects of his own plan reflected in Scheer's, particularly with the Conservative candidate's interest in ramping up security at Canada's southern border. He plans to hire an additional 250 officers to join Canada's Border Services Agency.
Of course, while Scheer has vowed to exercise "compassion" when strengthening enforcement at the border, his approach would still be a departure from Trudeau's, with the Liberal government focused on boosting Canada's immigration intake with a plan to accept 350,000 immigrants a year by 2021.
