Now that Canada has opened its tourism market to China, visas will not be as difficult as before.
The content of the invitation letter should be simple and clear, stating who to invite, the gender of the invited person, the birthday passport number, the time, what to do, how long to stay, and who will bear the expenses. No modifiers are needed.
As for unmarried women, don't worry. If she has been to other countries before, it will be good visa materials, as long as the visa officer's worries are eliminated.
If only one invitation is sent, it will be sent to the first of the four people, but the other three people should be stated in the invitation (of course, the basic information of the four people can be listed in the invitation).
There must be an invitation letter in English.

This is the way to invite new structures. You can rework it yourself.
The business invitation letter is going to Canada to do something, so it would be better if each of you were linked to the business of your friend's company. In addition, you should also issue relevant certificates to prove your professional and economic status in China.
So, in short, if you choose the invitation method, you will carefully prepare the relevant types of visa materials. Good luck!
