what is the tier for colleges like mohawk , fanshaw , seneca ? do graduate certificates are valuable and do companies give preference to them while searching job?
Don't think colleges come under tiers. They are based on reputation i.e Humber is most probably number one in Toronto and Seneca is considered to be good among colleges as well based on : employability, recognition, previous alumni records, transfer credit pathways, entrance percentage requirements, etc. Mohawk & Fanshaw are decent but are lower reputed compared to Humber.
Graduate certificates being valuable for employment is dependent on the overall profile as a lot of factors are involved such as : the field, labour market forecast and the general scope etc. other than just the certificate benchmark.
In the last three years, the average annual economic growth in Toronto accelerated to 3.7%, but is expected to slow down to 2.08% over the next five years up to 2022 or even beyond due to COVID-19.
