Most students work part-time during their studies at a university. Be it either as a TA, RA, GA, in Library, or others like Technician (your case).
CIC doesn't specifically deny accepting this as a valid experience, it only alludes that it is not possible to get sufficient experience while being a student.
Did you work for 15 hrs per week at least, for a period of 2 years. Then you do satisfy the requirement per se.
But your doubt as to whether this could cause an issue is genuine (it being not a standard experience). So only someone having the same experience can tell better.
I personally think they would accept it, because they accept part-time experience in general, for which wages are drawn.
Keep asking, someone else with that kind of experience might reply.
All the best,
Regards
