Inquiry about Hebrew classes (Montréal)

Hello

I am a Phd student inLaw at Montreal University. I need to take Hebrew classes as it would help me with my thesis. Does anyone happen to know where i can take some good Hebrew classes that are not too expensive? I took some classes for 2 weeks a few years ago and speak fluent Arabic (which is veeeery close to Hebrew)...please let me know if you have any suggestions or ideas where i can go...thanks a lot!
