While I’m sure you are correct (as you usually are), the BC law doesn’t actually mention the word Compilation Engagement in those areas of the Act that you refer to; 47(1)(c)(i) nor 47(2) nor 47(1).
It seems that a lay person must make the leap that one of the words “certification, declaration or opinion” include or mean a Compilation Engagement communication.
Considering it is more than a 13,000 word document, presumably written by intelligent people, one would expect they could have made it crystal clear what is and what is not considered offside for a person who doesn’t hold a CPA designation. The word “compilation” is not written once in that entire document.
