I don't think it would be any use for you. First of all the employer won't pay you in Canadian currency. Secondly that would be just a MNC work and in this situation of the company, you giving this way they won't ever issue you a refrence letter and will not be ready to give you LMIA in future since you are serving them in much less value. I bet they won't give you the same salary as your on site collegues. Why to waste your time in this situation as this will be counted as foreign work experience, disrupt your routine due to entirely different rime zones whereas you can gain the same working in your home country in the normal routine. Though I can be wrong.
