Hi
No, as long as the wages are not lower than what was approved on the LMO.
I attended the LSUC immigration conference at the end of Nov. SC was there talking about the new rules, particularly STS (substantially the same). Said that SC would allow a 2% differential (higher or lower) in wages and that if the wage increases more than that, the job needs to be re-advertised because Canadians may have wanted to apply with an increased wage. I don't know what CPC-V is doing about this with higher wages as I've never seen one refused with these circumstances. But I am hearing about more STS audits for employers.
To the OP, don't want to scare you as it will probably have no impact on you in particular unless SC decides to do an audit and pulls the LMO. Chances of that are probably slim.
