I am not suggesting that they are deliberately spreading the disease but lectures are virtual anyway and the 30 day ban was set for a reason and it is a worry that people are appearing to bypass the rules and increase the risk for little real benefit.
I want to make a few points. The government feels that student travel is essential and non-discretionary for good reason.
1. Many programs are not virtual and it is difficult to deliver them as such.
2. If you aren't in Canada for atleast 8 months, you do not get CRS points for PR.
3. There are tax residency headaches which arise because of limiting travel. If I travel after end of May I'm a tax resident of my home country, in addition to Canada. Many of such cases end up in expensive and lengthy court battles.
4. When people pay to study in Canada, they are also paying for co-op and/or residency in a foreign country.
Again I don't see what the problem is if all rules are diligently followed. I don't think scapegoating international students is fair when:
1. A lot of Canadians are not following quarantine and/or using land borders to cross in. My friend also told me that mask enforcement is extremely lax.
2. If I check stats, only 10k international students crossed in every month Q1 last year. Even if you assume that many crossed in this year, even though the numbers have dropped significantly because of Covid and quarantine requirements, the numbers don't add up. Inspite of 3 Covid tests(1 at home and 2 in Canada), 3 day hotel quarantine, 11 day home quarantine, screening for symptoms at both exit/entry points, even if 0.5-1% of the people are affected, you only have 1.5-3 people/day infected on average, which is nowhere near the 8500/day cases being reported.
