***PLEASE REMEMBER*** that only certain passes count. Unfortunately the BC compass website calculates all the trips you have done and not just the trips you are eligible to claim. You still need to manually go through and subtract all non-eligible trips before using that number on your tax return.
The CRA website list the eligible passes:
These passes must allow unlimited travel within Canada on:
You can also claim the cost of Short-term passes if:
Each pass entitles you to unlimited travel for at least 5 consecutive days; and you buy enough of these passes for unlimited travel for at least 20 days in any 28-day period.
Electronic payment cards if the card is used to make at least 32 one-way trips over a maximum of 31 consecutive days; and the card is issued by a public transit authority that records and provides a receipt for the cost and usage of the card.
