Hi guys I have given GRE and scored 1250 and do not plan to give the GMAT...are there any universities in Canada where I can apply for MBA? and I do not have any work experience

Well I myself is a novice out here but still I can suggest you to mail the schools and ask them if GMAT can be replaced by GRE. There are only a few Business Schools in Canada. So mailing all of them would not hurt that much.

The following schools in Canada will accept GRE scores instead of GMAT:

Concordia University
Lakehead University
St. Mary's University
Simon Fraser University (Financial Risk Management)
University of Calgary
University of Manitoba
Univ of New Brunswick ? Saint John
University of Toronto

Of course, your lack of work experience will not be well received by most schools on this list, so keep that in mind.
