System Availability

Last modified on February 17, 2023

Online submissions to LTSA are accessible between 6:00 am and 11:00 pm, Mondays to Saturdays.

Target system availability during periods of accessibility is 99%.

During overnight hours after 11:00 pm, LTSA generates data updates for taxing authorities across BC and completes system backups. In addition, availability may be interrupted due to routine system maintenance windows, which are:

  • Thursdays: 8:00 pm to 11:00 pm
  • Sundays: all day

Customers may not be informed in advance of service outages occurring during routine system maintenance windows. LTSA has built its systems with redundancy in mind. Redundant data centres allow LTSA to continue to provide service should a data centre be temporarily disabled. Systems are also constantly monitored by LTSA for availability.

System Disruption Procedures

As with all electronic systems, occasional service outages or interruptions affecting LTSA’s online services may occur. These disruptions could affect some or all of LTSA’s online services. In the event such issues suspend access for a period greater than 30 minutes, where practical, LTSA will issue communications to affected customers following the guidelines set out below.

Some system outages or interruptions may be due to matters within LTSA's control, while others could originate with external providers. Regardless of the source of disruption, the following communication procedures will be followed:

  • The first 30 minutes after the onset of the system disruption are spent diagnosing the issue and investigating the source. Since most system disruptions are identified and resolved within this timeframe, no communications are issued.
  • If LTSA or its system providers are unable to resolve the issue within 30 minutes of its onset, we will endeavour to alert customers to the disruption through communications that include any available information about its anticipated resolution. The manner of communications will depend on the nature of the system problem but will typically include posting a message acknowledging the disruption to the myLTSA login page and through Twitter.
  • After 60 to 90 minutes, LTSA may issue instructions to delay filing, dependent upon the date and time of day the system disruption is occurring.
