Dear Krishna
we have "only" the "Best practise" document. Not very helpful here. SVT Set up is "technically" easy but from business point of view "not easy" as you must collect the "data" to decide the "relevance"; and this is >80% company specific.
Conclusion; you need to discuss with your customer the "legal US/CA" demand and then try to map it to SAP EHS.
EHS SVT is, as SDS distrbution process or WWI process, designed as a "framework" which can you can use and "customize"; Especially the customizing is (or can be) very customer specific (and on top anything depends on the fact: do you buy content yes or no) in many cases you will need customer specific function modules the implementation as such is (can be) very company specific. The situation depends as well on the fact if or if not the SAP standard data model is used (or not)
For "US" specialities you will find some threads here. There is no thread which i know about Canadian stuff. Check document
Substance Volume Tracking using SAP EHS MANAGEMENT

PS: SVT can be as "complex" as WWI set up or SDS distribution part, It depends more or less: is the customer "satisfied" if you "just" use the SAP default values (For US and CA: there is nothign; but you can use as starting point REACH data); according to my experience: might be the case but (but for some customizing activies: > 80% probability that you have to prepare it from scratch by yur own) not very probable; but for "demo" use quite good starting point
PPS: be aware of the fact that there are some "US" specific sub solutions done via SVT; check the document; some threads exists here discussing these "specialities"
Many parallel threads show that for SVT set up the "detail" might be important (as with WWI set up)
