Hi Essaad,

I am not sure what part of Canada you are in so my suggestions are general - it is a big country and there is a lot of variation in opportunities between cities/provinces.

Here are a few recruiters that have a fairly big national presence:

SI Systems - http://www.sisystems.com//index.cfm?mg=cp.hp

Eagle Placement - http://www.eagleonline.com/

Sapphire - http://www.sapphireca.com/

These agencies focus on contract placement, which may be difficult for you to get if you are a junior BA.  However they sometimes have permanent placements and would be a good place to ask about other agencies that focus on permanent employee positions.

Here's one that is more employee focused:

David Aplin - http://www.aplin.ca/

Other than that use Indeed and look for BA jobs in your area - look for positions that list a specific HR contact and call them up directly to learn more about what they're looking for. Good luck!
