I read Piggy's post on VJ that Marily is stopping in Toronto before she heads to Boston.
I hope that the pigster have done his homework to see if she is eligible to transit through Canada under the TWOV program (she currently qualifies under 3 of 4 criteria - country (Philippines), hold US Visa & have onward boarding pass, but not sure about the 4th - approved airline (do not know what airline she plan on).
Also, I hope that he gave her enough connection time. And that she arrives before the U.S. in-transit pre-clearance facility is closed.
