I had locked myself outside the house with my cellphone and keys inside while housesitting my friends' home. Since it was a Sunday afternoon I wasn't expecting anyone to come save me anytime soon or even pick up my call.
After calling a few other locksmiths and not receiving a response, I called Ottawa Locksmith. Within twenty minutes of calling them, I had a locksmith on my front step opening the door. He was kind and did the job quickly.
