You are correct, when Meadow was born they became a Common Law Couple, with CCB being determined by based on family income. As such DM not filing taxes would impact MBM's CCB payments.I believe this was unpacked and discussed quite extensively, months ago. Maybe someone else remembers the outcome better than I do. But I think it was a missed deadline from 2024, not 2025. This led to a whole discussion of common law marriage, which, I believe in Canadian law, DM and MBM were considered to be married under common law. For this reason, her benefits were impacted by his missed deadline.
I could certainly be wrong!
IMO
But for them to have not been receiving CCB in May 2025 it would have to have been due to DM not filing 2023's tax return.
2023's tax return determined the CCB benefit from July 2024->June 2025. 2024's tax return determines CCB from July 2025->June 2026.
At $1900/month that's a lot of money to leave on the table as a struggling family.
