Welcome to the FAQ website covering document topics in Canada.
my passport expires on the 8th november 2017 and i am travelling on the 14 August 2017 until the 4th September 2017. i applied for eta and it was approved and valid up to the 7th November. Should i applied for a new passport seeing mine is due for renewal and applied for new eta with the new passport or can i travel with it and renew it upon my return? will i be able to gain entry into Canada with the older passport with less validity?
You will be granted entry but likely only as long as your passport is valid. Given that you intend to leave before that, there shouldn’t be a problem.
