Hi does any one know if a certificate from the fibre optic association will qualify as a certificate of qualification from a Canadian province, territory or federal body ?
Almost definitely not - they're talking about things like a Red Seal certificate from a government certification authority like the Industry Training Authority.
What fiber optic association are you talking about, and is it a government body?
That's not how it works in Canada and that's not what the category is intended to be - here, the question is "do you have a certificate that is issued by an educational/certification body that entitles you to work in a regulated field in Canada?". For example, you need a trade certificate to work as an electrician. You have to pass exams in Canada to become a trade certified electrician.
If you become certified in the UK as an electrician, you'd most likely need to pass an equivalency exam in Canada to be entitled to work.
Unless I'm mistaken, it's unlikely that an FOA certificate is required to work in Canada. It's more likely that the kind of work that an FOA certificate teaches you to do would require another certificate in Canada, like limited-scope electrical worker, or cable installer, etc.
