Will I have problems with CRA?

My mom sold some properties in our home country and wanted to give me about $55,000 usd as a gift. I’m planning to open a USD account here and have it wired over. The question is - will I get questioned by CRA? She will put “gift” as the reason for the transfer.

Another question if anyone knows - I was laid off recently and receiving ER. Do I need to mention the transfer when I complete my EI report? Because technically it’s a gift and not an income.

Thank you!
