Travel restrictions do not make much sense

Our son lives 100 metres from Central Park in Burnaby, where he walks his dog every day. Central Park is in the Fraser Health Authority — but his apartment is across Boundary Road in the Vancouver Coastal Health Authority.

With the new travel restrictions, he could be fined for walking 100 metres but is allowed to drive 130 kilometres to the COVID-19 hotspot of Whistler, because it is also in the Vancouver Coastal Health Authority.

How does this make any sense?
