Narrative: On departure the gear lever was brought up but the gear stayed down. N door amber light on landing gear panel followed by landing gear inoperative. First Officer leg so Captain began part of the E&A checklist for associated caution (landing gear inoperative) as well as completing the landing gear failed to retract checklist. Captain asked the flight attendants to verify that the landing gear was still down in which the flight attendants called back and verified. He then contacted Maintenance Control then Dispatch. When the Captain came back; the flight crew switched controls and the Captain became the Pilot Flying and First Officer the Pilot Monitoring. A decision was made by the flight crew and Dispatch to continue the flight. Enroute the First Officer continued the checklist where the Captain left off with the Alternate gear extension and Dispatch called through the EFB and this time it was another Dispatcher and he said he agreed with the decision to go to ZZZ. Once completing all required checklists and comfortable with the landing the Captain performed a normal landing and was able to taxi clear of the runway and also taxi into the gate.


Second narrative: On normal takeoff at positive rate/gear up call/landing gear failed to retract. N door amber caution light on Landing Gear Panel illuminated; followed by illumination of Landing Gear INOP Master Caution light. Captain (Pilot Monitoring) referenced Landing Gear Fail to Retract checklist first; followed by LDG Gear INOP Caution checklist and finally the Alternate Gear Extension checklist. Captain asked the Flight Attendant to visually verify that the landing gear was still down; which they confirmed. Advised Flight Attendant that they would be updated with more information after coordinating with Dispatch; Maintenance Control and checklist completion. Captain called Maintenance Control to notify them of gear problem. Captain then contacted Dispatch to advise them of situation and crew's desire to continue to ZZZ. Dispatch and crew mutually agreed with decision. The Captain made the decision to be the Pilot Flying and have the First Officer switch to the Pilot Monitoring; as First Officer would be better suited to complete the Alternate Gear Extension checklist. During the first phase of Alternate Gear Extension checklist a call came in from dispatch through the EFB SatCom from a different Dispatcher (identified himself as filling in for original Dispatcher). Captain briefed Dispatcher and all parties mutually agreed on continuing to ZZZ. Checklists were completed and crew coordinated landing while also [requesting priority handling] with ZZZ approach control. Flight Attendant were told to prepare for a normal landing and given a time frame for landing in ZZZ. PA was made to passengers. Rationale to Continue to ZZZ: #1 priority to operate the flight safely; make the best decision based on the current conditions and situation at hand. Considerations were taken for additional fuel burn with gear down and current weather conditions. Based on prior experience conducting a maintenance ferry flight w/gear down in similar conditions with regard to fuel burn and performance. On taxi out prior to departure observed a lower cloud layer developing over the approach end. Had the appearance that ZZZ1 may be trending towards fog conditions.


Synopsis: Q400 flight crew reported landing gear failed to raise during climbout.
