I agree with ABG. YUL-FRA-BLR is the routing I would pick. Consider the alternative...

CO routing YUL-EWR-DEL-BLR
outbound: econ to YUL, long-long haul J to DEL, then dead tired you will take another flight in Y?
inbound: starting out in Y is not bad, then a nice long haul flight, then you have to do US Customs and Immigration in EWR... and your reward is an RJ flight to YUL followed by more Immigration formalities!

I lived in Asia for almost four years. Two hops, even with a longish layover in between, is much, much better and much easier on your body than 3 or 4 hops.

Welcome to FT and good luck with your routing.
