Write me a convincing letter of invitation for Tourist Visa

I want to invite my mother here in Canada for super visa. Write me a convincing letter to immigration. Just make a plot letter and I will add all the details such as my mother’s name and background including mine after the letter is done. I don’t want to provide my information and everything but just make a plot of the letter. I attached the details that should be included in the letter, 2 pages are fine.
