Hi There, I was traveling on April 25 2012, from Toronto to London Heathrow my flight was coded LH5335, and was operated by Air Canada AC856. I was at check in place 1;20 minutes early but was denied boarding I was wondering if there anybody else who ran into problem like my.

You were at the check in place 120 minutes early. What time did you actually attempt physical check-in?

[tayana2012]

one hour twenty minutes before I attempt physical check in together with my son, agent swiped our passports, got sits for us, asked us to put our check in bags on scale and then said "There is no way I can put you on this airplane, they already boarding".

[The_Judge]

I have no answer then. AC requires you be checked in no later than 60 minutes ahead of scheduled departure time. According to you, you were well ahead of that marker. If you were checked in by the agent, your check in information will have a time stamp on it. I suggest you write to AC and have them investigate this situation.

[tayana2012]

could it be overbooked flight?

[The_Judge]

Yes it could but that is no matter. You checked in within the policy set forth by the airline. If they denied you boarding and you were on time as you say you were, you are entitled to compensation.

In regard to what occurred, my flights were coded Lufthansa
the flight was operated by Air Canada, I and my son were present for check-in 1 hour and 20 minutes prior to departure.

Air Canada agents advised that this was insufficient time to complete
the check-in process, and directed me to the Lufthansa counter to
have our tickets reissued for a later flight. Unfortunately, the carrier was unable to re-issue our tickets, and advised us to contact your travel agent. Although I requested the carrier contact our travel agent directly, I was advise that they were unable to do so.

As a result, we were only able to travel 4 days later, on April 29th.

When our agent reissued our tickets, we incurred additional charges
of $840.00.

When I did present my self for check-in for my new flight, the process took less than 15 minutes.

Right after what happened I contacted Air Canada, Lufthansa and flightnetwork where I purchased tickets with request to investigate my situation, they were pointing arrows at each other, and were not willing to help me.
At last I contacted CTA and they helped me, I was reimbursed overpaid money by Lufthansa.

Now I wounder if I can clam consequential damage, and if I am entitle to such damage.

I was pregnant at time when all happened, was crying not sleeping, my residence is two hours of drive from airport, so my husband had to drive me back and forth. I don't know what to do now.

This sounds highly questionable. If the CTA intervened to get you refunded, you should now ask about denied boarding compensation. As your journey ended in an EU country and was coded as a Lufthansa flight, you might also try claiming under 261/2004, which would offer you additional compensation rights.

This is incorrect. Under EU261/2004 the operating carrier bears exclusive responsibility to compensate if applicable. AC being a non-EU carrier and their flight departed from a non-member state, the OP is not protected by the regulation. Canada does not have a similar legislation but AC have a policy in place to address overbooking.
Since LH reimbursed the fee levied to rebook the tickets, it sounds like they recognised that something had gone awfully wrong. They may also be willing to throw in some goodwill gesture if the OP insists.
