Why do I have a headwind in both directions?

I'm living the "uphill both ways" joke. I cycle to work, and I've always got a headwind, every day, in both directions. Why?

Friends told me "you're moving at speed, duh," so I dismissed it at an illusion... until I noticed I pass by a flagpole on my route. Every morning for the past week, when I approach by the flagpole, the flag is snapping in the wind, pointing right at me... eastward when I'm travelling west in the morning, and westward when I'm travelling east in the evening. I've noticed other things like dustclouds, bits of trash, and people's clothes blown in the wind, and sometimes knock-me-over crosswinds when I make turns.
I'm somewhat thankful for the extra workout, but it seems really odd that I would get headwinds in the most difficult direction, twice a day, every single day (feels like every day, but I've only been measuring for a week). Why on Earth?
Other details: I live in Montreal, most of my route is along Lachine Canal, although I cross the urban area of Verdun and over Champlain Bridge -- the bridge is perpendicular to the Canal, and yet the headwind is just as strong!
