TESL Canada is the national body that sets professional standards for ESL teachers in Canada — academically equivalent to the UK’s CELTA, and required by most Canadian language schools and government settlement programs.
OnTESOL was the first online TEFL/TESOL provider ever recognized by TESL Canada — since 2003. We’ve held that recognition continuously, and our courses lead to TESL Canada Professional Standards 1 and 2.

Real, unedited reviews from independent platforms. We don’t moderate them.
I completed the OnTESOL 120 Advanced course, and it was absolutely worth every dollar. The course gave me the skills I needed and helped me secure several job offers in Japan. The tutor was exceptionally knowledgeable and supportive.
I completed the 250-hour TESOL Diploma along with 3 specialist courses. Both tutors were excellent and very knowledgeable. I highly recommend OnTESOL to anyone wanting to become a qualified English language teacher without breaking the bank.
There were an extensive amount of lessons and detailed content. The combination of reading, video lectures, online real-time workshops and activities helped me greatly! My tutor gave very insightful comments from her personal teaching experience.
