There have been several questions regarding this so here is the answer:
The standard CFL blackout policy is as follows:
The blackout pattern for CFL games is 56 km radius from the stadium for cable television and 120 kms for conventional (CBC). There is one exception to this rule. The Province of Saskatchewan is subject to full provincial blackouts.
Notice to Bell ExpressVu Customers regarding Game Blackouts:
It has recently come to the attention of the CFL and Bell ExpressVu that a number of eligible customers are experiencing blackouts of their local CFL games.
Previously, ExpressVu managed blackouts by a six-digit postal code. Recently, Bell ExpressVu has changed their blackout procedures and it now employs only the first three digits of the postal code which has resulted in a wider blackout net than that mandated by the CFL.
If you are experiencing a blackout in your area, but are outside the 56km territory, please call your Bell ExpressVu customer service representative. Bell ExpressVu is currently working towards a solution.
