This isn't accurate in Canada, Chicken is far more expensive here. Pork is usually the more affordable meat choice.
I can get a full pork loin (for chops) for $9/kg, but chicken breasts or boneless skinless thighs are $12-15/kg. Those are Costco prices which are cheaper than regular price at a normal grocery store.
I just checked Thrifty Foods (Sobeys) and they have Boneless Skinless thighs at $23.80/kg, breasts at $22.70 per kg, and pork chops at $17.60/kg.
Even ground beef is cheaper than chicken $10/kg at Costco, and $14.30/kg at Thrifties.
Tofu is $6.60/kg
Edit: Anyone care to explain why you're downvoting me? This was posted in the Canada community, and these are my local prices in Canada in a major city.
