How do I register a trademark?

I recently came up with a new product idea (Based on an existing product so not a patent) and need to trademark the name in both Canada and the US. I’m looking for some people that have done this in the past, what a good company to use is, and what is cost you approximately… any suggestions?

Looks like its about $325
