Hi Palak,
The courses at any level in Canada trains you well for the job market, but they do not provide any guarantee on it. For managerial economics, you may check the skill shortage list and see if you have scope of jobs.

The Master of Arts in Community and Economic Development incorporates two distinct bodies of theory and practice: economic development and community development. It focuses on the importance of linking these two concepts in a model that integrates the development of social capital and community capacity with the economic development of the community.

Students from any stream can pursue economics honors.
Arts student can pursue BA (economics) provide that they have economics geography/ applied mathematics/economics or other related fields as one of the main subjects.
Commerce student can pursue B.Com (economics) provided that they had economics/business mathematics/pure mathematics/economic geography as one of the main subjects.
Science student can pursue B.Sc (economics) provided that they had mathematics as one of the main subjects.
This is general eligibility criteria, however it also depends upon particular admitting institute.

Dear,
Economics is bit tough in term of research, data analysis and statistics tools. If your foundation in maths is weak then it could be an issue.
I would suggest, you should consult with a renowned career counselor for better understanding of your caliber and interest.
All the best.
