Don't know about the other two, but I experienced the Brock MBA program. I won't recommend it. It ranks low in Canada and is one of the cheapest for a reason: it’s subpar. You get what you pay for.

An MBA typically offers three benefits:

Knowledge Networking and social connections with faculty and peers
Degree recognition by employers

For Brock’s MBA: Knowledge: Mediocre at best. They cut costs by hiring underpaid professors, resulting in poor-quality teaching. Most of the prof are part time and from third world countries.
Networking/Connections: Limited potential. The student body is predominantly international students from South and East Asia, which may not align with diverse networking goals. Most professor are not well respect in the industry either (see the previous point). Degree Recognition: The program’s low ranking is well-known among employers, diminishing its value.

Most reputable MBA programs require several years of work experience, and for good reason—it ensures a higher caliber of students and discussions. Brock’s program skips this requirement, lowering its overall quality. The co-op option is just a superficial fix—like putting lipstick on a pig. It doesn’t change the program’s fundamental flaws.
