New CRTC cellphone contract regulations come into effect tomorrow. Here is a synopsis. No more cancellation fees after two years. If you signed up for a three-year contract before June 3, 2013,you may leave your provider at no charge. Those who signed up for a three-year contract after June 3 but before Dec. 2 would still incur a penalty- but would be a 'small' one if they break their contract. Roaming charges would be capped at 100.00* A service provider must suspend national and international data roaming charges once they reach $100 within a single monthly billing cycle, unless the customer expressly consents to pay additional charges*. A service provider must suspend data overage charges once they reach $50 within a single monthly billing cycle, unless the customer expressly consents to pay additional charges*.
