Narrative:

On descent I smelled an odor that appeared to be coming from the lavatory. It became stronger and stronger; and smelled like an electrical smoke. Very shortly after; I noticed it becoming hazy in the cockpit quite quickly. There were no caution lights; master warning; nor was the lavatory smoke detector going off. We donned the oxygen mask and smoke goggles; and at that time the flight attendant called us. I was informed there was smoke in the cabin as well. I asked the flight attendant to try to locate a fire if able. The flight attendant was unable; I told him/her we had about 10 minutes until landing; bracing signals; and also that we were to evacuate the aircraft upon landing. We transferred controls to my side knowing that load shedding would shut down the first officer's instruments. We ran the smoke in aircraft checklist; while doing that I [advised ATC] and asked [for] priority to land. The pilot not flying ran the checklist leaning towards electrical smoke because it had a electrical smell. The smoke didn't appear to be disappearing yet getting any worse. Due to the lack of time and low altitude; I was unable to inform dispatch or operations. Landing was imminent so we proceeded to land and evacuate on the runway. The evacuation went quickly and smoothly; and there were no injuries.the checklist for smoke is quite the long checklist with many trees. Being so close to [destination airport] and at a low altitude; problem solving isn't timely. Having a quick checklist such as load shedding; dumping pressurization and land immediately would be fantastic to be used only when over an airport in which you can land at and at a low altitude.
