I don't doubt it. When I was on welfare, I had to log into an online portal every month and it asked me:
- Did you leave the province in the past 30 months?
- If so, for how long?
If you left the province for a prolonged period of time, you'd stop getting welfare. There's no actual verification that you stayed in the province. As long as you say that you didn't leave, you'll keep getting welfare benefits. The only time you ever have to talk to someone from the welfare office is once (or rarely twice) a year about your plans for the future.
If someone wanted to, they could go on welfare, leave the country, and never tell the welfare office. They'd keep getting benefits. The welfare offices and the bureaucrats that work in them are very overworked and they don't have the time or prerogative to actually check in on welfare recipients. This was back in 2022 though, so I'm assuming like everything else in Canada, it's gotten way worse since then.
