A) We've beaten this to death already. For debts of your type, the SOL is from when the debt went into default OR the creditor ought have known that it went into default.
The exact date a debt went into default can't always be defined because, sometimes, to judge when the creditor "ought to have known" when it occurred can be subject to some interpretation. Certainly, if one misses 2 or 3 consecutive payments, that would qualify. But another judge might conclude it started when the first payment was missed.
In most cases, it's a moot point because if someone is going to sue you, they won't wait until the last minute. An acknowledgment that renews an SOL must be in writing, and the SOL must not have expired already [unless it's something like a student loan which can revive an expired limitation period]. See Section 13(10) of the link below that says the acknowledgment must be in writing and signed to renew - but not revive a limitation period.

B) It may seem strange but the DLA (date of last activity) on a credit report is one of the most misunderstood and misused terms even by credit bureau staff - a fact which I find astounding. This probably due to 2 reasons.
1. The DLA (date of last activity) is defined somewhat differently by TransUnion and Equifax than the various provincial credit reporting acts describe it.
2. The 2 bureaus make no effort to clearly define what they mean by it either on their websites or on their written reports. And if you talk to staff there, you are likely to get several different answers.
If you call your average creditor's reporting officer to the bureaus, you'll find even more confusion. Some (including major banks) maintain it's when the debt was written off. Others say it's when a a payment was last made to a collection agency. Yet, others maintain that it was when a creditor or collection agency last reviewed your file, while many maintain it was when the debt was last sold off. HELLLLPPP!
I remember asking experienced staff at the bureaus about this matter who, in turn, quoted me non-existent legislation. Several didn't even know what the statute of limitation on a debt was. True, the latter is unrelated to credit reporting; but how in the world could you work in the industry and not know that?
It's hard to fathom that the meaning of so important a term is left ambiguous to the general public, but it is. Furthermore, it's hard not to infer the equivocation and ambiguity is deliberate.
Credit reporting bureaus are big money making operations and the demarcation lines between between credit reporting, enforcement and protection are becoming increasinly blurred. We have ex-collection agency presidents running credit bureaus. We have ex-collection lawyers woking with Ministry of Consumer Protection heads who used to work in the sheriff's seizure dept. and so on. Maybe, Deanna Natale will be the next Minister of Consumer Protection.
When you dispute a credit item, the credit bureau is supposed to thoroughly investigate the details of the dispute with the creditor as per consumer protection legislation. What actually happens is they make a quick phone call to the credit reporting lackey over at the company in question and ask them if the data they've sent is "ok." The person on the other end of the line likely doesn't even look at it in many instances, and even if they do, they are unlikely to understand or even care about what the credit reprting acts mandate. No letter, fax or any such thing is generally sent and none is asked for.
To the credit bureau, your complaint is nothing more than a nuisance and a necessary cost of doing business which eats in to profits. And so responses are made as cursory as possible, officious denials to the contrary. That's why I tell people to save all their old records and be prepared to fight. They are likely to need them.
