Yeah, that's right. Apparently, each province of Canada are taking turns to picket. It is to my understanding that there are service problems as routes have not been delivered due to staff shortages, and postal workers have been required to perform forced overtime so they want better working conditions. But this kind of irks me because I have a friend who works as a letter-carrier for PO and he found strategies to finish his 8 hour's work in approximately 4 hours. But it is not possible now because they have added duties/responsibilities so it is not possible for him to complete his work in under 8 hours. 
I have been paying bills online because I do not want my bills in the mail to arrive to the destination late.
