Not that easy to convert
I converted my Canadian licenses to FAA in 2001. I can tell you right now the only ones that convert are the Private and ATP. (Unless things have changed since then). In other words all your certificates will amount to an FAA private pilot license based off your Canadian private. In fact if you loose your Canadian one for waterver reason your FAA private is void.
You will need to take a written and practical test for your commercial and instrument and only a practical test for the multi-engine. Keep in mind the practical test standards are different in the US. So don't expect to just show up and pass...you will need to get signed off by a CFI just like you did in Canada. The good news is the hours count. This is no simple task and also expensive.
