Moving at this point likely wouldn’t make sense. You’d have start all over again and it is much harder to secure PR than it was 2 years ago. The family also probably doesn’t have a history in the other provinces so would either not qualify or not receive enough point to get selected. The MPNP backlog is very bad but there are backlogs in all or almost all the other provinces as well.
MPNP doesn't have as much backlog as they did a year ago, their current assessment is over 1000 and total less than 3000, at this point they're just priortizing inlanders and still being slow about it
