How to actually decide
Since neither publishes pricing, the only comparison that matters is two live quotes for your specific address and equipment needs. Ask both the same four questions: total monthly rate after any promo period, exact agreement length, early-cancellation cost, and who owns the equipment at the end. The answers vary by promotion and province, which is why we don’t print numbers a sales rep would immediately contradict.
