Canadian High Interest Savings Bank Accounts

I currently have a TD Bank $US Visa credit card associated with my TD US "Borderless account" that is included with TD's Select Service Package. I get this package for free by keeping CDN $5,000 in my Select Service account. However, this TD $US Visa credit card has no rewards associated with it. Is there any $US Visa/Mastercard or whatever that a Canadian can get that has rewards attached to it that I could use instead? I live close to the border and as a result shop in Bellingham where I use my Canadian American Express card at the Bellingham Costco (I have been lead to understand that not having a US address means I can't get a $US Amex card for Costco). I also shop at Cost Cutter Walmart Best Buy etc. where they of course take my $US Visa. Does anyone know if there is anyway to get a $US Visa card that has some kind of reward (cash back, gifts, air travel), that I could legitimately get?
Thanks ahead of time for any information provided (both good and bad).:smile:
