Not exactly.
If you are unable to work due to Covid (i.e. you are sick or taking care of someone who is, you’ve lost work due to Covid etc.) then yes, there are benefits you can apply for, it was a Covid benefit for the first chunk of pandemic, now it’s all under EI (employee insurance), which we all pay into off our pay cheques.
Generally you only go onto EI if you’ve lost work due to no fault of your own and are actively searching for new work. But they’ve expanded and broadened it now due to covid.
But you can’t just international travel, then do your 14 day quarantine and get paid during that 14 days. And now you have to stay in an approved hotel upon arrival for up to 3 days (at your own expense) until you have a negative test result, and then you can finish quarantine at home.
