I would presume I should post Service Canada SIN scams here on the SSA board, perhaps it can be renamed SSA/CSSA as the truly lame south border of Nunavut calls are getting more common here in Canada. Like the CRA I normally will start with; “Bonjour, parlez-vous français, comme je ne parle pas anglais?” The scammers will therefore DEMAND “SPEAK ENGLISH!” Heck, some officers have threatened me with arrest for speaking Canada’s other official langauge… 
@Darrell64#115058 We take SIN numbers on BobRTC just mention in the comments that it’s Canadian social insurance/pensions, not SSA
