IMO, governments are being unrealistically narrow and inflexible on vaccinations' priorities. On one hand vaccinating the most vulnerable early will likely save lives; on the other, when it comes to herd immunity, every additional immune person contributes to herd immunity.
That said, this couple committed blatant intentional fraud. C$2300 "Monopoly Money" plus a few days' jail time is probably proportional to their fraud (I doubt that the Yukon Territory is a hotbed of Covid spread).
