コロナウィルス感染拡大に伴い、カナダ政府は留学生に関し、授業が実施されている間につき週２０時間の労働時間の制限を即時撤廃すると発表しました。ただしエッセンシャルサービス（医療関係やインフラ関係、食糧やその他の生活必需品の供給に伴う職種など）に関わる職種のみでの適応となります。

コロナウィルス感染拡大に伴い、一部の職種では（従業員の確保について）厳しい局面にあり、カナダ国内の留学生がそのニーズに応えられると政府は認識しています。

例えば、間も無く卒業を迎える生徒も含め、カナダでは何千もの留学生が医療・救急関連のプログラムを専攻しています。この一時的な制度改正によって、訓練を積んだ医療従事者が現在の医療機関におけるスタッフ不足を補うと考えられます。

この撤廃は2020年8月31日までです。

また、許可証に「医療関係では働けません」などの制限がかかっている場合は、継続してその職種では働けませんので、ご注意下さい。

Temporary rule change aimed at helping health-care facilities, other workplaces under pressure

April 22, 2020—Ottawa—To help battle the COVID-19 outbreak, starting immediately, the government will remove the restriction that allows international students to work a maximum of 20 hours per week while classes are in session, provided they are working in an essential service or function, such as health care, critical infrastructure, or the supply of food or other critical goods.

During the COVID-19 outbreak, workers in certain roles and industries have been under considerable pressure, and the government recognizes that international students who are already present in Canada will help meet the challenges of the pandemic.

For instance, thousands of international students are studying in health- and emergency service-related programs, including many who are nearly fully trained and ready to graduate. This temporary rule change provides health-care facilities with access to additional well-trained workers at a time when they are badly needed.

International students and their employers should consult Public Safety and Emergency Preparedness Canada’s Guidance on Essential Services and Functions in Canada During the COVID-19 Outbreak to determine if the work the student is doing would allow them to work more than 20 hours per week during the academic session.

This temporary rule change will be in place until August 31, 2020.

Statistics Canada reported that in 2017–2018, more than 11,000 international students were enrolled in health-care programs at Canada’s universities and colleges, representing about 4% of health-care students at that time.
