Cell phone service for Canada -> U.S. if no sim card?

Thanks for the replies. So it looks like no burner phones with calls to the US are available in Canada.

I can get a plan like those mentioned upthread, except actually better--$25 for:

500 minutes (5¢ overage)
500 sent messages (5¢ overage)
Unlimited incoming messages
1 GB data

BUT the problem with Verizon is that Verizon CDMA-only phones, like mine, will stop working in Canada by the end of this year, possibly as early as September 1. That's why I'd like to have a different phone entirely.
