Welcome to the Q&A Forum

Saw a major increase in traffic from analytics on the 12th and it's stayed steady. The problem is, our numbers are not correlating with the data from analytics, so I'm guessing its a Google issue, otherwise it would be awesome if we saw that positive effect here in the US lol.

It's better to sort out the problem in the source rather than patching it with rel canonical. One thing you can do to help the situation is to teach Google about your URL parameters in Google Webmaster Tools: url-parameters.PNG
