I believe that if the child was born in the DR it would be quite difficult to get it a CDN passport. Check with Imigration Canada to find out. You might also find the info at Service Canada.
I am quite confident...
a child from a Cdn citizen qualifies for Cdn citizenship..
Father's brth certif.... baby's birth certif showing that person as father and =--POOF !
I have done this for UK passports from a grandparent's birth certif
you just need to prove the lineage........might need a marriage certif...dunno
wait..... Cdn resident or citizen..... might be a difference
