Yes but AFAIK, you cannot enter India on a tourist visa now. I don't see the point in getting a visa that you cannot use?
The entry visa is also like a tourist visa AFAIK. Please call BLS and clarify it with them and see if you can travel to India on an entry visa. If yes, ask them if you can submit your surrender and your entry visa applications together. Also, call a few airlines and check with them if they'll allow entry visa holders to board the plane. The last thing you want is to go to the airport and then discover that you're not eligible to travel.
You do not have to wait until your surrender process is done. Also, surrender process takes 3 - 5 weeks, not 2 weeks. The processing time has now been updated to 8 weeks for surrender for Toronto jurisdiction. I submitted my application on 31st August and received my surrender certificate in the mail today.
Trying to confirm the same from BLS and CGI Toronto. Thanks
