Fully credit the source when you paraphrase information. This is accomplished similar to citing other sources. For example, "According to..." or "So-and-so states...," followed by or prefaced by the information used, is best practice.
Quote the material directly when you use information word-for-word. For example, "According to Statistics Canada, 'Local and international factors affecting agriculture fluctuate in an unpredictable manner, and farmers have to adapt rapidly... .'"
Use the name of the organization over the name of the website whenever possible. For example, instead of writing, "According to www.statcan.gc.ca," write "According to Statistics Canada."
When the website you are referencing doesn't have an official name, include the URL, followed by information about why the website is credible. For example, while citing an Internet source that doesn't have an official name for an article about caring for dogs, write "www.petcareeducation.com/dog/, a website dedicated to educating the public about the care of dogs." Be careful in these situations that the website is credible. You can get an idea by looking at the "About Us" page.
