Patenting a product

I have developed a wearable product which can be used to detect earthquakes. It is completely radiation free. After all the testing I got the sample product developed by a product development and design company called Spark Innovations in USA. I had a session with them and they told me that the product has potential to stand out in market. They told me to get a patent for my ideas. I am from Canada and I would like to know what would be procedure for patenting? How much would it cost? What documents do I have to provide? I know its a lengthy procedure. I am just new to this and I am looking for some good advice :)
