Do all car seats sold in Canada meet Transport Canada standards?

All seats sold on the Canadian market must bear the National Safety
Mark attesting to the fact that the authorized manufacturer has
certified that the seat meets the prescribed Canadian safety standards.
Transport Canada monitors the manufacturers’ testing and certification
programs through its own independent compliance-testing program.

What is the National Safety Mark?

The National Safety Mark is a Crown trademark, incorporating a unique
alphanumeric identified that the Minister of Transport authorizes and
assigns to individual manufacturers to affix to all car seats intended
for the Canadian market. The National Safety Mark represents the
manufacturer’s declaration that the car seat complies with all
applicable safety standards and regulations in effect on the date of

What is NCAP (New Car Assessment Program) crash testing?

All vehicles in the U.S. and Canada must undergo NCAP crash testing
at 56 km/h to simulate a severe car accident. Child car seats are only
required to crash test at 48 km/h. At 56 km/h, an NCAP test can have
almost double the crash impact force of a standard 48 km/h car seat
crash test. NCAP is a “severe-accident” survivability crash test for a
car seat and the child who must depend on it. Radian seats successfully
NCAP crash test at both 20.5 kg RF and 30 kg FF without relying on the
top tether.

Does the 30 kg lower anchor limit apply to all UAS equipped vehicles?

No. It is important to read the manual for the weight limit when using UAS. The 30 kg lower anchor limit for Radian car seats is only for vehicles manufactured after September 1, 2005 when vehicle lower anchor strength requirements were increased.

What is the benefit to having a unique removable rear-facing base on a convertible?

The unique base of the Radian simplifies and stabilizes rear-facing
installation. Radian performs extremely well in rear-facing crash tests.
A removable base allows Radian to be positioned lower on the vehicle
seat for improved forward-facing safety and convenience.

Do all car seats have side impact protection?

No. Currently, there is no U.S., Canadian or European regulatory side- impact testing requirements. A manufacturer can claim “side- impact safety” without meeting any standard. All Diono car seats provide reinforced side- impact protection, and some models offer the increased protection of an adjustable head support. Diono’s RadianRXT and Monterey™ models were side- impact tested to the widely accepted German standard established by ADAC, Europe’s largest automobile club.
