I'll forward this list to him.I do not think that is right.
I did a head on comparison of US (Seattle) and Canada (Victoria). Numbers are not very different. Prices are from IGA and Save on food. I tried keeping the brand names similar and sub-kind similar. Left side is USD in Seattle, right is in Canada with prices in CDN.
Mushrooms : 7.99USD : 9.00 CDN
Tofu : 4.49; 3.99
Tomato (150): 0.82 : 0.82
Cauliflower: 3.99 : 3.49
White onions 1 KG : 7.7 : 5.5
Green Beans(450): 2.47 : 4.5
Spinach : 2.59 : 2.99
Skimmed Milk 4L: 6.59 : 5.79
Whole milk 4L : 7.60 : 6.15
Chicken Breast : 4.84 : 11.37
Whole Chicken 1.5KG : 15.48 : 13.11
Large Eggs (12) : 6.29 : 7.49
Rice Basmati (907 Grams) : 6.99 : 4.95
Whole Wheat (Aashirwad) 9100 grams : 40.0 :20.0
Note : These are food items and groceries. I am not comparing a diner / restaurant cost. That might be higher because labour is expensive in Canada.
Indian restaurants are seemingly more expensive down south.
Example, a plate of idly and dosa cost around 40usd, while in gta it would be 25-30 cad
