L1A blanket stamping in Canada

I received a blanket L1B visa denial in Chennai earlier and then entered US with L1B individual visa. Later my employer applied L1A individual when I am in the US itself and it is approved. now for extension of L1A I was asked to go to Canada for L1A blanket stamping.
I would like to know if the previous blanket visa denial for L1B would affect the current blanket visa stamping of L1A or would each case be dealt independently?

No, this is not a problem. Employer has governing authority on this visa type and most times it is approved without question. Each case is also adjudicated based on current merit independent of previous rulings.
