Yup, we can't shut the tap off completely but we can turn it down as much as possible.
As my mom would say, it's like "slamming the barn door shut after the cows have all gotten out".
Sure, you can possibly reduce the number of cases that are brought in the country with travel restrictions. But, you're not restricting
everyone so you're not really solving the problem (perhaps that action makes people feel better about the situation, and makes them "feel" like something's being done, but how much does it solve a problem when you have 119 land border crossings between Canada and the USA that are still being utilized, at least to some degree?).
I know the argument will be, "But we have to be able to import and export goods!". Let me assure you there are a ton of things moving across the border, in both directions, that aren't essential by any stretch. It seems nonsensical, given many of the other restrictions, to not start giving a ton of scrutiny to exactly what goods are being transported to and fro. If new strains are the concern, then EVERYTHING that's not
essential should be halted (and since the government has not had a problem telling people what kind of travel is or is not considered "essential", they should be similarly equipped to determine what goods also fall within that same category and which ones do not). And cross border workers should be equally restricted from crossing as they, too, pose a risk......perhaps an even greater one than a single-trip leisure traveler, because they are CONTINUOUSLY bringing the risk into each country on a daily basis, with no testing or quarantine requirements.
All it takes is one person to bring in a new strain. These newest rules and restrictions may reduce the risk, but it certainly won't eliminate it. And once it's in the country, the spread and transmission of the virus that follows isn't the solely the fault of the person who carried it there. That responsibility lies with the residents of that country and how well they practice
their Covid protocols.
The initial border closures and restrictions, which drastically reduced the number of people traveling, hasn't solved the problem: in fact, cases have ballooned since March DESPITE those closures. As much as I'd like to be proven wrong, I sorely doubt these latest additional restrictions will be the magic cure that everyone wants to see. It's easy to blame the leisure travelers for the current situation but there are a whole lot of other possible carriers/spreaders that have, and will continue to, travel uninhibited and continue to potentially spread the virus as they do so.
I would hate to see cross border workers and truck drivers to be the next groups to feel the sting of the coronavirus effect, but everyone else has been feeling the burn for months, so they honestly should count themselves lucky. If the government is going to take a hard line, it needs to be a hard line for all.
BTW damo, this post was not intended at all to argue with you specifically. Just a starting post to share my thoughts.
