Hello
I wrote the certification test for CBET in Canada(same one as in the US)and it is not easy. You are allowed 7 hours to complete the exam and it covers a wide range of topics and equipment. I definately learned from the experience.
Certification is not legally required in Canada(yet) but employers are free to require it of thier employees if they want. My employer does require a biomed tech to become certified.
The nice incentive for the tech is a 10% raise in pay once certification is achieved. There is also a certification exam for biomed techs who do hemodialysis technical service full time.
