The driver's licence has no relevance.
The SIN is on your income tax returns and must be produced but no one, a lawyer or otherwise, can use it to gain information.
The employment details are not confidential.
But your income may be and if the lawyer had more than your income tax returns then it very well may be a conflict.
So you may be correct and that means the new lawyer will need to step down and in fact you may be able to file a complaint with the law society as well.
But if the only income information the lawyer who did your mortgage had was on your income tax return then the lawyer acting now would not have and could not have received any confidential information.
Do you see what I mean?
It will come down to whether the income information went beyond what you would normally want to reveal and so if it goes beyond the Return there may be a conflict.
