Right now, in order to travel, it is up to everyone to analyze the situation according to their situation, including:
Insurance: Are you covered for your travels by your group or private insurance, whether in connection with COVID-19 or for any other medical emergency? Check with your insurer. More info in this article.
Entry requirements: each country has its own regulations. Some will only let in nationals or bi-nationals, others will require a negative COVID-19 test.
Requirements upon return to the country: only permanent residents and Canadian citizens can return to Canada at this time. If you are in Canada on a Visa, it is not advisable to leave the country.
A possible quarantine on your return: at this time, if you return to Canada from abroad, you will have to self-isolate for 14 days.
Changes: as the situation is still unstable, some borders may close and flight options may become more restricted.
So take all this into consideration before moving forward.
