Telus is a phone/ISP company, they're pretty much uninvolved other then the ability to send emails from a @gmail.com address for their customers needs. Spammers are just utilizing that for malicious purposes with spoofed headers. As for how they got your email, the spammers could very well be working from the US too, Telus is just a tool. But then again on the internet boundaries matter less and they could be halfway across the world and got your email from a random online leaked list.
