My Aunt is currently visiting the USA (Boston) will stay there for another 3 months. I would like to invite her to Toronto and visit me and my family. I have all her passport information including photocopies of her passport etc. She doesn't know how to apply for Canadian visitor visa online. Can I apply for her visitor visa online on her behalf myself from Toronto. Please advise.

Yes, you can apply on her behalf.
I hope you also have her financial or employment documents, those are important in getting approved for a Canadian visitor visa.
