据油价网2021年5月25日报道，由于额外管道输油能力增加以及油砂产量增加，今年加拿大对美国的原油出口将会增加，并补充说，由于可找到的生产商很少，对重质原油的需求也一直在上升。
加拿大的管道日出口能力将至少增加约42万桶，同时油砂中的重质原油产量将有所提高。加拿大著名能源运输公司安桥公司表示，最大的产能增加将来自于将于今年第四季度完成的3号线扩建。
扩建项目将把管道的日输油能力从39万桶提高到76万桶，并使安桥公司能够接受更多的产能预留请求。现在，根据Argus的报道，安桥公司必须拒绝52%的管道输油空间申请。
由于管道运力不足，加拿大向美国出口的原油越来越多，不得不通过铁路运输。美国密歇根州州长格雷琴·惠特默日前下令关闭了安桥公司的5号线，称其对环境构成风险，之后，管道问题也导致了美加关系的降温。安桥公司拒绝关闭这条每天能够运送54万桶原油和液化天然气的管道。
在惠特默州长要求关闭输油管道的最后期限之前，渥太华在一份声明中说：“这起案件引起了人们对历史框架的担忧，几代人以来，美加关系一直是基于这个框架成功管理的。”声明还说，密歇根州州长的这一举动“威胁破坏国际合作关系的重要方面”。
这就是为什么管道3号线的扩建会受到加拿大石油生产商的欢迎，而安桥公司的另一条管道——从哈迪斯蒂到怀俄明州卡斯珀的Express管道的扩建输油能力也会日增5万桶。安桥公司预计在第二季度内完成扩建项目。

Canada To Boost Oil Exports To The U.S.
Canadian crude oil exports to the United States are about to increase this year as additional pipeline capacity comes online and oil sands output increases, adding that demand for heavy crude has also been on the rise with few producers available.
Pipeline export capacity will rise by some 420,000 bpd at least, the report noted, while production of heavy crude in the oil sands improves. The largest capacity addition will come from Enbridge's Line 3 expansion, to be completed by the fourth quarter, according to the company.
The expansion project will boost the pipeline's capacity from 390,000 bpd to 760,000 bpd and will enable Enbridge to accept more requests for capacity reservations. the company has to reject 52 percent of requests for space on the pipeline.
Because of the pipeline capacity shortage, rising Canadian exports of crude to the United States have had to be transported by rail. Pipeline issues have also recently led to a cooling in U.S.-Canadian relations after Michigan Governor Gretchen Whitmer ordered Enbridge's Line 5 shut down, claiming it posed an environmental risk. Enbridge refused to shut down the pipeline, which carries 540,000 bpd of crude oil and natural gas liquids daily.
"This case raises concerns regarding the efficacy of the historic framework upon which the U.S.-Canada relationship has been successfully managed for generations," Ottawa said in a statement ahead of Gov. Whitmer's deadline for shutting down the pipeline. The move by the Michigan Governor "threatens to undermine important aspects of that cooperative international relationship," the statement also said.
This is one reason why the expansion of Line 3 will be welcome by Canadian oil producers, as will the 50,000-bpd expansion of another one of Enbridge's pipelines—the Express pipeline from Hardisty to Casper, Wyoming. Enbridge expects completion of the expansion project in the current quarter.
