On the Canadian cars the DRL and the twilight sentinel are combined into a Canadian only module(different than the rest of the world). The Canadian cars lack the the twilight sentinel adjust knob on the dash.

Are your DRLs blinking or your headlights? DRLs are dimmer than the headlights.

The twilight sentinel will power on the low or high beam depending where you leave the high/low switch.

If you are not good at electronics a replacement module and sensor would help diagnostics unless it is a wiring problem.

You can unplug the module and lose both DRL and twilight sentinel.

If the car has been modified with LED or HID headlights they will mess with the DRL.

I am betting on HID.

More questions,
Does it look like it is the DRLs half bright doing this or is it the headlamps at full bright?

Are the tails doing this at the same time?

If the dimmer switch is in high beam position is the high beam indicator flicking on and off with the headlamps ?

Where in Canada are you ?

I'm in Ontario I'm not real sure about what lights are actually flashing il have to investigate that more but the High beam indicator dose flash on the dash with the lights and it is also on all the time no matter if the high beams are on or the low

Only the head lights do it not the tails

Are they flashing together or are they alternating?

Might have a relay going bad in the underhood fuse box.

What relay would that be?

The headlight circuit has a fuseable link powering the headlight switch which has a built in breaker, this goes to the high/low switch and then to the headlights.
The DRL/twilight sentinel module is fed by a fuse and does have several relays inside it:
As the OP said:
you can hear the day time running light module under the pass side kick pannel clicking away
