Ontario Labour Laws: this info at a high level can be found in this handy poster you could put on a slide and show to the participants poster http://www.labour.gov.on.ca/english/es/pdf/poster.pdf
1. Always good to have an understanding of law, and reporting practices. I'd refer to the Ontario Ministry of Labour site and its multiple links http://www.labour.gov.on.ca/english/es/
b) A secondary gov't site discussing similar issues and providing multiple links http://www.tbs-sct.gc.ca/chro-dprh/hrh-eng.asp
2. Charity Village has a section called "Topics" that deals with HR related issues from a nonprofit/charitable viewpoint.https://charityvillage.com/topics.aspx
3. General discussion of different areas of HR, albeit from an american standpoint (since they briefly mention the IRS), can also be helpful.http://www.inc.com/encyclopedia/nonprofit-organizations-and-human-resources-management.html
4. For a Canadian perspective, this site offers info and multiple links in their discussion of hiring/managing employees, and workplace safety. http://www.canadabusiness.ca/eng/page/2749/sgc-35/#toc-_hiring_and_managing_employees
5. http://cuteoverload.com - animal pics for stressful times:)
If there's time, and it's not being highlighted elsewhere, I'd also suggest seeking legal counsel when preparing contract templates (at least in the start up phase).
Differences Between Employees and Contractors
There are pros and cons of hiring employees and contractors. While it may be easier in some cases to hire someone as a contractor, it is often preferred by individuals to be hired as employees because of associated benefits from both government and potentially the organization. Although some prefer being hired as contractors and forgoing some benefits for the flexibility and sometimes higher pay that they can put into their own investments en lieu of benefits.
Today, it is very common for non-profits and industry to hire contractors who really should be employees. But where does one draw the line?
Here is an article from CFIB which shows the right questions to consider: http://csci-how-to-start-a-nonfor-profit.wikia.com/wiki/Employees_vs._Contractors_Article
