Canadian snow load help please
(OP)
Can anyone please inform me of the ground snow load requirement for Prince Edward Island in Canada? I've called the building department there as well as the NRC Institute for Research in Construction, and neither of them know the answer. Unfortunately I have no access to the National Building Code of Canada.
I found a vague reference to approximately 61 psf, but I'd like some "official" confirmation before we order roof trusses.

For "Charlottetown" PEI, NBCC-2005 1/50 year load are:
Ss=2.7 kpa
Sr=0.6 kpa
Wind (1/50)=0.60 kpa
(1/10)=0.46 kPa
Hope this helps.

You might want to involve a local, licensed, professional engineer.
Further, if you're just looking for the snow load for a product manufacturing reason, the local building department should be able to tell you.
Drifting, balanced and unbalanced, as well as sliding snow are all explicitly required by the NBCC. I strongly urge you to seek a P.Eng. (PEI) Structural Engineer to assist you.

LOKSTR, thanks for the additional information!

Under Canadian law it is the Engineer who commits an offence when offering services to the public without a license (and in some provinces this must also be through a registered company in prosession of a valid "Certificate of Authorisation".
I can understand your position, and know that you are not trying to break any laws, however I must warn you that from what I have seen, you are. You may stand to be banned from practice in PEI (and potentially other Provinces, as you would be required to check the box "Yes" for "Have you ever been disciplined by, or been subject to sanction from, any jurisdiction" [I'm paraphrasing, but you get the idea, and it's pretty much a no-go for getting a license from what I understand].
You should be very careful. I would encourage you to contact the PEI Professinal Engineering Assosciation. http://www.engineerspei.com/ They may be a small province (sort of a Canadian Rhode Island) but they'll have very similar, more than a little midly protectionist, engineering laws.

Your snow covered home is presently not snow covered. Infact in Ottawa, the home of your alma mater, it's 31 deg. C today.
Chill out, go figure.

Perhaps you got the floor sweeper. I agree they should have been able to respond to your perfectly reasonable request. It is surprising sometimes in small jurisdictions what level of Municipal competence exists!
Residential portions of the Canadian Code can be designed by anyone as long as the design stays with in that part of the code!
RE: Canadian snow load help please
Whether or not you need to be an engineer to apply something, if you ARE an engineer there is an implicit understanding that the person has engaged you because of your training... Something tells me that slta isn't just going to go through all of the tables in Part 9 and ensure they comply with the whole of the residential code; He/She will be applying specialist knowledge based on the loading... That IS Professional Engineering, even if there is a code which covers the work.
Just my opinion, and when last I checked following the rules is pretty much the halmark of due diligence.
