Drive while suspended is a Part 3 offence, so the 7 day deadline you are likely referring to is the one that applies to Part 1 offences. In Part 3 offences, the Crown has 6 months from the date of the offence to commence proceedings against you. If you were given a summons at the road side telling you when to attend court, the officer STILL has to get the 'information' sworn before a judge or justice of the peace for the proceedings to commence. The judge/JP is always able to refuse the case for the information and the case never even proceeds (though that is very rare). Other times, they will charge a person 'after the fact' whereby the information is sworn and THEN it is served on the defendant at a later date. Check your paper work to see how they are proceeding against you. Most likely you will see its via Part 3 of the Act, which is a VERY different game altogether. Your paralegal should have been able to decipher this for you---if they can't, run!
By the way, don't forget to understand the rules for POA offences set out as a regulation under the Courts of Justice Act. See Reg. 200 for more insight on what forms the officers must use.
