Government websites and publications can often be a good source for content for an open textbook, because it is often distributed under an open license. However, licensing varies, and so you should always check before including government content in your work.
Canadian Government Websites
Most government of Canada websites and publications are covered by an Open Government Licence. Here is an example of acknowledging a source under Statistics Canada’s data licence:
Source: Statistics Canada, name of product, reference date. Reproduced and distributed on an “as is” basis with the permission of Statistics Canada.
Often, Canadian government websites stipulate that the reused image or resource not be used for commercial purposes. If this is the case, then add this line to your attribution: “This image cannot be used for commercial purposes.”
