CRA rules are "You can claim a maximum of 2 trips per year for other travel for each member of your household". Nowhere do they state any age restrictions. Here's a little more information on the Northern Residents Deduction for travel.
To claim your Northern Residents Deduction (NRD) for Travel Benefits, you'll need to meet the CRA requirements for claiming the NRD first. If you determine you do qualify, you can claim the Travel Expenses for a trip you took anywhere.
Just remember that you are only allowed to claim the "lowest" amount of the three requirements:
- The taxable travel benefits received from your employer - Box 32 of your T4 slip.
- The actual amount you paid for your trip.
- The lowest return airfare between the airport closest to your residence and the nearest designated city to that airport.
