This is very straight forward. You've received a Part 1 Provincial Offence Notice.

I recommend that you read Provincial Offences Act section 3, 9 and 76, and sections with respect to appealing.
The officer has 30 days to write you a new ticket and serve it to you. Or within 6 months of the alleged offence they can serve you with a Part 3 summons.
It stands to believe that your ticket may have been switched with someone else. Hopefully, the other party doesn't just pay the ticket because that would result in an automatic conviction.
You can seek a paralegal/counsel, but your best course of action is to do nothing. If you're found under s9 of the Provincial Offences Act "Deemed not to dispute charge", you will receive a conviction letter in the mail and at this point you can file an appeal.
The golden numbers here are that the officer can still charge you with a Part 1 offence within 30 days of the alleged offence, and Part 3 summons within 6 months of the offence.
So if your appeal process takes place within a 6 month period, they can lay a Part 3 summons charge for this offence.
