AdSense issue: changing country associated with the account

A few months ago, I moved from USA to Canada. My YouTube channel is currently monetized by my US AdSense account. After searching for a while online, I noticed that I should change my AdSense account to be in Canada, according to the link here (https://support.google.com/adsense/answer/2628816?hl=en)

The process seems to be complicated, as there is no direct and simply way to just "update" the country in your Google Adsense account to Canada. There are a few steps that need to follow, including:

1. cancel and close the existing Google AdSense account that was created in USA
2. reapply another Google AdSense account using the address information in Canada
3. wait for a few days to get approved
4. change the settings of YouTube channel to associate with the new Google AdSense account

Today, I just cancelled my US AdSense account, and am waiting to see how the process works. I will update later once I get some news on this matter.

Really, Google could make this process much simpler by allowing the users to change the country info in an existing Google AdSense account.

[update 2017-03-24] Just got an email from Google AdSense team saying that my new application was not approved. It looks that the process is not very smooth. There are some issues that I need to address, including the email account, the info, and the YouTube/website URLs. Very disappointed.
