Evidence products prepared or updated with funding from COVID-END in Canada can be accessed below. These evidence products are shared through our twice-a-month Canadian spotlights and through many of our dissemination partners. If you want to receive an email containing hyperlinks to our Canadian (and global) spotlights twice a month, subscribe here.

Our evidence products can take many forms:

  • response based on existing resources
  • one-off rapid evidence profile or rapid synthesis
  • living evidence profile or living evidence synthesis that is updated regularly.

Our evidence profiles and evidence syntheses vary in:

  • the effort that goes into them, which we measure in the number of hours or days that a very large team of highly experienced staff devote exclusively to the task (e.g., four hours to three days for evidence profiles and for updates to living evidence profiles; five to ten days for rapid syntheses and for updates to living evidence syntheses)
  • the type of best evidence they include and whether they also include a jurisdictional scan.

Below we provide examples of how these evidence products can vary.
