yes, there is an application guide on the CIC website where the forms are located. Look for the country(region) specific guide for your spouse's country of citizenship. that is where you will want to start.
the first post on the first thread on this board also gives a great breakdown of the process. keep in mind the processing times listed are not accurate for today's processing.

for more up to date information regarding how long it takes for the visa office in the country of your spouse, find the thread specific to that visa office and ask what the average time is. note the times listed on CIC's website are not averages and do not represent what most applicants face.
once you've done some research and start compiling the information needed, come back to the forum for specific questions. go through the first few pages and look for topics that you need help with first. there is a lot of information already provided. we are not going to be able to walk you through filling out the forms. that is not what we are here for. we are here to guide and support you when specific questions come up when navigating the process. if you need someone to help you fill out the forms and put together your package, then you will need to seek help from a consultant or lawyer. most people do this themselves and it's not necessary to pay someone money to do work you can do yourself. this forum generally has better knowledge and information because we have gone through the process.
best of luck!
