Don't forget the AIP

the latest editions of the aeronautical maps, charts and other

AIP Gen 0.1
9. RELEVANT DOCUMENTS AND CHARTS
9.1 To ensure compliance with CAR 233.(1)(h), a pilot in command
must have access during flight to appropriate documents and
charts selected from the following:
a. VFR: ERC, WAC, VNC, VTC and ERSA for the route being
flown.
b. IFR: ERC, IAL charts and ERSA for the route being flown,
and also for the departure, destination and alternate airfields to
be used. In addition, where visual navigation is required, the
pilot in command must have access to appropriate WAC, VNC
or VTC.
It doesn't say you need to carry a copy of your flight notification, but it is always a good idea to carry one, just in case you need it.
