Haven't heard anything bad about
CANPAC Language Institute.
They are foreign owned, so don't think they will take you for a ride. They also have top clients as Nike, Pepsi and Wrigley Chewing Gum. Schools dealing with such large clients usually tend to look after their teachers both remuneration wise and in fairness.
They have also been around for a while, so hence you would have the peace of mind they will pay you and honour their contract with you.
If they offer you a job, I would surely take it!
