Looking for guidance on canadian SMS gateway/relay providers

Could anyone point me towards a reputable and useable SMS gateway provider that provides canadian phone numbers? I know I can send to Canadian numbers via Twilio/Tropo, but I'd like to receive texts at a Canadian number (because texting the USA from Canada is ridiculously expensive on most Canadian cellular providers). Every provider I've found either hides their API/pricing and wants me to talk to a salesperson or seems simply unuseable. Are there any Twilio clones serving the Canadian market?
