Postal strike in Canada?

A generation ago a postal workers' strike would bring to a halt much of life and the economy as bills failed to arrive, people failed to pay them, &c. Now, however, the threat of a postal strike seems far less disruptive. After all we pay bills by phone or over the internet. We send packages via courier services such as UPS and FedEx. There would be inconvenience to be sure. But we are simply far less dependent on conventional postal services than we used to be.
