Outstanding education, good faculty, and unquestionably a top university, however… the administration and support services are frequently beyond poor, terrible, and unbelievably bad.
Administrative procedures are tangled and Kafkaesque. It could be related to the Quebec Unions that employ them, and their French legacy of bureaucratic apathy, unhelpfulness, and an unwillingness to accomplish their tasks efficiently.
Also, there is a large party culture in Montreal, which is easy to get lost in, yet living there is inexpensive, as is going out.
I’d go back there for an education.
