I agree with marycatherine, the Canadian School in Doha is not recommended. The school has nothing to do with Canada except for the name.
Copying a provincial curriculum and claiming affiliation is not appropriate.
Too many issues were occurring which led teachers to leave in the middle of the school term. The school has recently appointed a new principle with the aim to fix the problems but I wouldn't trust to put my kids there.
As a Canadian you are entitled to put your kids in the American school or if you choose in any of the British schools.
