While not revealing specific numbers, the online-only Ontario Cannabis Store says ”a high volume of orders” means customers may have to wait a bit longer for their marijuana.

The site had promised to deliver products within three business days when pot was legalized Wednesday.

But a message on ocs.ca now informs customers their orders could take up to five days to be delivered.

”The response to cannabis legalization has resulted in a high volume of orders.  Please expect your order to be delivered within one to five business days.  We apologize for any inconvenience,” the message reads.

It’s not yet clear what impact a potential Canada Post strike would have on delivery, however, the government has said it has a contingency plan in place to ensure orders are delivered in the event rotating postal strikes start Monday, but would not elaborate.
