The Panda algorithm was originally introduced in 2011, and penalizes sites with content that Google considers to be of poor quality. Sites that are penalized by Panda tend to see a decrease in ranking for almost all search phrases, including location phrases such as Winnipeg.
In some cases, Panda's effect can be quite drastic, but the good news is that this particular algorithm update is meant to benefit small businesses that employ good SEO practices. That means that you can recover, and that your larger competitors might have taken a hit as well.
