In case this helps anyone: I just heard that anyone 21 and younger is exempt from the hotel quarantine if financially dependent on their parents, or maybe 22+ if still dependent. Seems unclear to me, and obviously YMMV upon arrival.
I haven't found this online but someone forwarded me an email from Health Canada to that effect.
ETA: I've heard that yeshiva guys in the US are eyeing this exemption on on this page but obviously a huge YMMV especially with hundreds of bochurim crossing in the next ~10 days.
I have spoken to Canadian border control and they confirmed that this exemption (in the link that you said bochurim are eying) is only meant for students who regularly travel to the US - and they define regularly by daily or weekly, at the most.
But, the hotel quarantine does have an exemption of "an unaccompanied minor or unaccompanied dependent child" (
https://www.canada.ca/en/public-health/services/diseases/2019-novel-coronavirus-infection/latest-travel-health-advice/mandatory-hotel-stay-air-travellers.html#a2). The quarantine Act that carves this out defines a "dependent child" as the same meaning as in section 2 of the Immigration and Refugee Protection Regulations (
https://orders-in-council.canada.ca/attachment.php?attach=40252&lang=en). Those regulations define a dependent child as " is in one of the following situations of dependency, namely, (i) is less than 22 years of age and is not a spouse or common-law partner, or (ii) is 22 years of age or older and has depended substantially on the financial support of the parent since before attaining the age of 22 years and is unable to be financially self-supporting due to a physical or mental condition." (

So, every unmarried student/bochur
traveling alone and under 22 should be exempt from the hotel quarantine (but not from the regular quarantine).
As mentioned earlier on this board, anyone who can show a positive PCR test from 14-90 days before entry to Canada is free from the hotel quarantine.
