There are almost no refugees arriving to Canada at the moment due to travel restrictions. We may be talking about a handful of people. Nobody is forcing elderly people travel to Canada at the moment. Heading to a hotel with your luggage is not a very strenuous activity especially when you have luggage on wheels. Knowing that you will have to manage your own luggage you may want to pack with that in mind. There will likely have people to help lift luggage into whatever transportation that is provided if needed. Quarantine hotels are required in order to attempt to prevent the spread of the covid mutations into the community. If one of your parents had one of the covid mutations the driver of the car taking them home could get infected. I assume that the Transportation provided to the hotel quarantine will have significant precautions to protect the driver. People quarantining are often not quarantining with only those Who were travelling. With the new mutations a whole households would be guaranteed to get infected. Although you may be happy for your whole household to get infected the health system can not risk whole households getting infected. Travellers quarantining with their non-traveling family members should actually quarantine for longer than 14 days. With the 14 day current requirement in most provinces there are risks that a non-traveling household member could lead to community spread. In Alberta people will need to quarantine for 24 days if a household members tests positive for a mutation. This may be in place in other provinces.

There are already 3 cases in Ontario where you have had community spread through buildings where multiple people from different households have been infected. The thought is that infection has spread through a common area like the elevator. These new variants are extremely contagious.

Hotel rooms are comfortable. After long flights people will probably just want to sleep or rest for a few days. We are talking about a hotel in a 1st world country and not to a tent in a refugee camp. People will have pretty comfortable surrounding, food, a warm shower, etc. Nobody should want to risk catching covid or want to risk spreading covid to their family. Long covid isn’t getting much attention. Even with a mild case of covid that doesn’t require hospitalization you could have longterm sever health issues. Today I was watching some cases on the news in the UK. Even children have ended up with long covid. Imagine having your healthy child end up in wheelchair and so fatigued that they can’t attend school just because of a covid infection.
