Canada House Center is such a scam for teachers. You wouldn`t believe the things I saw when I was there. None of the teachers I knew had any kind of work VISA and CHC was doing all kinds of things to keep the teachers under the radar. They became upset with me when it became clear I was insisting on doing things legally. You can actually get into a lot of trouble by the games they play because you wind up being forced to play fast and loose with immigration which can have consequences when you cross out or back into the country. The administration based in Loja, in my case, suffered from a serial mendacity. CHC has this idea that they own teachers and this manifisted itself once in them threatening us with deportation if we didn`t do things their way.
