The H&C application process is a completely separate process from applying for PR through the spousal stream. If you want to submit an H&C application, then you need to use the application package here:

From the Guide:
In order to be considered for an exemption from the usual requirements of IRPA, you must:
•clearly indicate in your application the specific exemption(s) you are requesting.
•provide all details related to your request including the reasons why you believe an exemption(s) should be granted on H&C grounds.
•demonstrate that there are sufficient and compelling reasons for you to be granted an exemption allowing you to apply for permanent residence from within Canada.
Your responsibility
You are responsible for making sure that all circumstances and factors that you wish to have considered are provided in your application. This must include any hardship you believe you will suffer if you are not granted the exemption(s) you are requesting, including why the hardship would be unusual, undeserved or disproportionate. For example, if you are claiming hardship arising from circumstances in your country of origin, your supporting documents should include:
•the hardship you anticipate,
•whether the hardship would be faced in all areas of the country of origin or country of habitual residence,
•whether you ever sought assistance from the authorities, including police or non-governmental organizations, to change or improve your situation in your country, and
•if you have not sought assistance from within your country, you must provide reasons why you have not done so.
